(1) Represents an aggregate of 139,990,000 shares of Class B Common Stock, par
    value $.01 per share (the "Class B Common Stock"), of Viacom Inc. (the
    "Registrant") available for issuance under the Viacom Inc. 2004 Long-Term
    Management Incentive Plan (the "2004 LTMIP"). In addition, this Registration
    Statement shall also cover any additional shares of Class B Common Stock
    which become issuable under the 2004 LTMIP being registered pursuant to this
    Registration Statement by reason of any stock dividend, stock split,
    recapitalization or any other similar transaction effected without the
    receipt of consideration which results in an increase in the number of the
    Registrant's outstanding shares of Class B Common Stock.



<PAGE>


(2) Pursuant to Rules 457(h) and 457(c) of the Securities Act of 1933, as
    amended (the "Securities Act"), the proposed maximum offering price per
    share is based on the average of the high and low prices of the Registrant's
    Class B Common Stock on the New York Stock Exchange consolidated reporting
    system on April 15, 2005 and is estimated solely for the purpose of
    calculating the registration fee.

(3) Pursuant to Rule 457(h) of the Securities Act, the proposed maximum offering
    price per share is based on the average weighted exercise price of (i)
    14,500,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on January 26, 2005, (ii)
    4,550,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on July 1, 2004, (iii)
    3,400,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on April 1, 2005, (iv)
    245,098 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on March 15, 2005, (v)
    150,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on July 19, 2004, and (vi)
    50,000 shares of Class B Common Stock subject to outstanding but unexercised
    options granted under the 2004 LTMIP on June 2, 2004, for a total of
    22,895,098 shares of Class B Common Stock subject to currently outstanding
    options and is estimated solely for the purposes of calculating the
    registration fee.

(4) Pursuant to Rule 457(p) of the Securities Act, the aggregate amount of the
    registration fee (i.e., $571,003) is being offset by $200,812, representing
    the dollar amount of the registration fee previously paid by the Registrant
    in respect of 15,000,000 unissued shares previously registered on Form S-8,
    filed February 9, 2001 (Registration No. 333-55346). Accordingly, the
    adjusted registration fee for this Form S-8 is $370,191.

Item 5.  Interests of Named Experts and Counsel.

         Michael D. Fricklas, Esq., Executive Vice President, General Counsel
and Secretary of the Registrant, who has rendered an opinion stating that under
applicable state law the shares of Class B Common Stock to which the
Registration Statement relates will be, when issued, delivered and paid for in
full, validly and legally issued, fully paid and non-assessable under the laws
of the State of Delaware. As of December 31, 2004, Mr. Fricklas held 46 shares
of Class A Common Stock and 1,406 shares of Class B Common Stock and held
exercisable options to acquire 592,500 shares of Class B Common Stock and
non-exercisable options to acquire 177,500 shares of Class B Common Stock.

Item 6.  Indemnification of Directors and Officers.

         Section 102(b)(7) of the Delaware General Corporation Law ("DGCL")
allows a corporation to include in its certificate of incorporation a provision
eliminating or limiting the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except in cases where the director breached his duty of loyalty to the
corporation or its stockholders, failed to act in good faith, engaged in
intentional misconduct or a knowing violation of the law, willfully or
negligently authorized the unlawful payment of a dividend or approved an
unlawful stock redemption or repurchase or obtained an improper personal
benefit. The Registrant's Amended and Restated Certificate of Incorporation (the
"Viacom Charter") contains provisions that eliminate directors' personal
liability, in certain circumstances.

         Section 1 of Article VI of the Viacom Charter provides that the
Registrant shall indemnify any person who was or is involved in or is threatened
to be involved in any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he is or was a director, officer, employee or agent of the
Registrant, or is or was serving at the request of the Registrant as a director,
officer, employee or agent (including trustee) of another corporation,
partnership, joint venture, trust or other enterprise, to the fullest extent
authorized by the DGCL, as the same exists or may hereafter be amended, against
judgments, fines, amounts paid in settlement and expenses (including attorneys'
fees), actually and reasonably incurred by him in connection with such action,
suit or proceeding. Notwithstanding the foregoing, except with respect to
proceedings to enforce rights to indemnification and advancement of expenses,
the Registrant shall indemnify an indemnitee in connection with a proceeding (or
part thereof) initiated by the indemnitee, if and only if the Board of Directors
of the Registrant authorized the bringing of the action, suit or proceeding (or
part thereof) in advance of the commencement of the proceeding.

         The Viacom Charter provides that to the extent that a present or former
director, officer, employee or agent of the Registrant has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred
above, or in defense of any claim, issue or matter therein, such person shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by that person in connection therewith. The indemnification and
advancement of expenses provided by, or granted pursuant to, the indemnification
provisions of the Viacom Charter shall not be deemed exclusive of any other
rights to which a person seeking indemnification or advancement of expenses may
be entitled under any statute, by-law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in that person's
official capacity and as to action in another capacity while holding such
office. Without limiting the foregoing, the Registrant is authorized to enter
into an agreement with any director, officer, employee or agent of the
Registrant providing indemnification for such person against expenses, including
attorneys' fees, judgments, fines and amounts paid in settlement that result
from any threatened pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, including any action by or in
the right of the Registrant, that arises by reason of the fact that such person
is or was a director, officer, employee or agent of the Registrant, or is or was
serving at the request of the Registrant as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, to the full extent allowed by law, except that no such agreement
shall provide for indemnification for any actions that constitute fraud, actual
dishonesty or willful misconduct.




<PAGE>


         The Registrant may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Registrant,
or is or was serving at the request of the Registrant as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
Registrant would have the power to indemnify him against such liability under
the provisions of Article VI of the Viacom Charter.

         Pursuant to Section 5 of Article VI of the Viacom Charter, the
Registrant has purchased certain liability insurance for its officers and
directors as permitted by Section 145(g) of the DGCL.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

         See Exhibit Index.

Item 9. Undertakings.

         (a) The undersigned Registrant hereby undertakes:

              (1) To file, during any period in which offers or sales are being
         made, a post-effective amendment to this Registration Statement:

                   (i) to include any prospectus required by Section 10(a)(3) of
              the Securities Act;

                   (ii) to reflect in the prospectus any facts or events arising
              after the effective date of this Registration Statement (or the
              most recent post-effective amendment thereof) which, individually
              or in the aggregate, represent a fundamental change in the
              information set forth in the registration statement;

                   (iii) to include any material information with respect to the
              plan of distribution not previously disclosed in this Registration
              Statement or any material change to such information in the
              Registration Statement;

         provided, however, that the undertakings set forth in paragraphs (1)(i)
         and(1)(ii) do not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed with or furnished to the Commission by the Registrant
         pursuant to Section 13 or Section 15(d) of the Exchange Act that are
         incorporated by reference in this Registration Statement.

              (2) That, for the purpose of determining any liability under the
         Securities Act, each such post-effective amendment shall be deemed to
         be a new registration statement relating to the securities offered
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof.



              (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         (b) The undersigned Registrant hereby undertakes that, for purposes of
determining liability under the Securities Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
that is incorporated by reference in this Registration Statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.




<PAGE>

         (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

------------------------- ------------------------ ------------------------ ------------------------- -------------------------
(1) Represents an aggregate of 139,990,000 shares of Class B Common Stock, par
    value $.01 per share (the "Class B Common Stock"), of Viacom Inc. (the
    "Registrant") available for issuance under the Viacom Inc. 2004 Long-Term
    Management Incentive Plan (the "2004 LTMIP"). In addition, this Registration
    Statement shall also cover any additional shares of Class B Common Stock
    which become issuable under the 2004 LTMIP being registered pursuant to this
    Registration Statement by reason of any stock dividend, stock split,
    recapitalization or any other similar transaction effected without the
    receipt of consideration which results in an increase in the number of the
    Registrant's outstanding shares of Class B Common Stock.
(2) Pursuant to Rules 457(h) and 457(c) of the Securities Act of 1933, as
    amended (the "Securities Act"), the proposed maximum offering price per
    share is based on the average of the high and low prices of the Registrant's
    Class B Common Stock on the New York Stock Exchange consolidated reporting
    system on April 15, 2005 and is estimated solely for the purpose of
    calculating the registration fee.

(3) Pursuant to Rule 457(h) of the Securities Act, the proposed maximum offering
    price per share is based on the average weighted exercise price of (i)
    14,500,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on January 26, 2005, (ii)
    4,550,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on July 1, 2004, (iii)
    3,400,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on April 1, 2005, (iv)
    245,098 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on March 15, 2005, (v)
    150,000 shares of Class B Common Stock subject to outstanding but
    unexercised options granted under the 2004 LTMIP on July 19, 2004, and (vi)
    50,000 shares of Class B Common Stock subject to outstanding but unexercised
    options granted under the 2004 LTMIP on June 2, 2004, for a total of
    22,895,098 shares of Class B Common Stock subject to currently outstanding
    options and is estimated solely for the purposes of calculating the
    registration fee.

(4) Pursuant to Rule 457(p) of the Securities Act, the aggregate amount of the
    registration fee (i.e., $571,003) is being offset by $200,812, representing
    the dollar amount of the registration fee previously paid by the Registrant
    in respect of 15,000,000 unissued shares previously registered on Form S-8,
    filed February 9, 2001 (Registration No. 333-55346). Accordingly, the
    adjusted registration fee for this Form S-8 is $370,191.

Item 4.  Description of Securities.

         Not Applicable.
Item 5.  Interests of Named Experts and Counsel.

         Michael D. Fricklas, Esq., Executive Vice President, General Counsel
and Secretary of the Registrant, who has rendered an opinion stating that under
applicable state law the shares of Class B Common Stock to which the
Registration Statement relates will be, when issued, delivered and paid for in
full, validly and legally issued, fully paid and non-assessable under the laws
of the State of Delaware. As of December 31, 2004, Mr. Fricklas held 46 shares
of Class A Common Stock and 1,406 shares of Class B Common Stock and held
exercisable options to acquire 592,500 shares of Class B Common Stock and
non-exercisable options to acquire 177,500 shares of Class B Common Stock.

Item 6.  Indemnification of Directors and Officers.

         Section 102(b)(7) of the Delaware General Corporation Law ("DGCL")
allows a corporation to include in its certificate of incorporation a provision
eliminating or limiting the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except in cases where the director breached his duty of loyalty to the
corporation or its stockholders, failed to act in good faith, engaged in
intentional misconduct or a knowing violation of the law, willfully or
negligently authorized the unlawful payment of a dividend or approved an
unlawful stock redemption or repurchase or obtained an improper personal
benefit. The Registrant's Amended and Restated Certificate of Incorporation (the
"Viacom Charter") contains provisions that eliminate directors' personal
liability, in certain circumstances.

         Section 1 of Article VI of the Viacom Charter provides that the
Registrant shall indemnify any person who was or is involved in or is threatened
to be involved in any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he is or was a director, officer, employee or agent of the
Registrant, or is or was serving at the request of the Registrant as a director,
officer, employee or agent (including trustee) of another corporation,
partnership, joint venture, trust or other enterprise, to the fullest extent
authorized by the DGCL, as the same exists or may hereafter be amended, against
judgments, fines, amounts paid in settlement and expenses (including attorneys'
fees), actually and reasonably incurred by him in connection with such action,
suit or proceeding. Notwithstanding the foregoing, except with respect to
proceedings to enforce rights to indemnification and advancement of expenses,
the Registrant shall indemnify an indemnitee in connection with a proceeding (or
part thereof) initiated by the indemnitee, if and only if the Board of Directors
of the Registrant authorized the bringing of the action, suit or proceeding (or
part thereof) in advance of the commencement of the proceeding.

         The Viacom Charter provides that to the extent that a present or former
director, officer, employee or agent of the Registrant has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred
above, or in defense of any claim, issue or matter therein, such person shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by that person in connection therewith. The indemnification and
advancement of expenses provided by, or granted pursuant to, the indemnification
provisions of the Viacom Charter shall not be deemed exclusive of any other
rights to which a person seeking indemnification or advancement of expenses may
be entitled under any statute, by-law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in that person's
official capacity and as to action in another capacity while holding such
office. Without limiting the foregoing, the Registrant is authorized to enter
into an agreement with any director, officer, employee or agent of the
Registrant providing indemnification for such person against expenses, including
attorneys' fees, judgments, fines and amounts paid in settlement that result
from any threatened pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, including any action by or in
the right of the Registrant, that arises by reason of the fact that such person
is or was a director, officer, employee or agent of the Registrant, or is or was
serving at the request of the Registrant as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, to the full extent allowed by law, except that no such agreement
shall provide for indemnification for any actions that constitute fraud, actual
dishonesty or willful misconduct.
The Registrant may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Registrant,
or is or was serving at the request of the Registrant as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such, whether or not the
Registrant would have the power to indemnify him against such liability under
the provisions of Article VI of the Viacom Charter.

         Pursuant to Section 5 of Article VI of the Viacom Charter, the
Registrant has purchased certain liability insurance for its officers and
directors as permitted by Section 145(g) of the DGCL.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

         See Exhibit Index.

Item 9. Undertakings.

         (a) The undersigned Registrant hereby undertakes:

              (1) To file, during any period in which offers or sales are being
         made, a post-effective amendment to this Registration Statement:

                   (i) to include any prospectus required by Section 10(a)(3) of
              the Securities Act;

                   (ii) to reflect in the prospectus any facts or events arising
              after the effective date of this Registration Statement (or the
              most recent post-effective amendment thereof) which, individually
              or in the aggregate, represent a fundamental change in the
              information set forth in the registration statement;

                   (iii) to include any material information with respect to the
              plan of distribution not previously disclosed in this Registration
              Statement or any material change to such information in the
              Registration Statement;

         provided, however, that the undertakings set forth in paragraphs (1)(i)
         and(1)(ii) do not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed with or furnished to the Commission by the Registrant
         pursuant to Section 13 or Section 15(d) of the Exchange Act that are
         incorporated by reference in this Registration Statement.

              (2) That, for the purpose of determining any liability under the
         Securities Act, each such post-effective amendment shall be deemed to
         be a new registration statement relating to the securities offered
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof.

              (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         (b) The undersigned Registrant hereby undertakes that, for purposes of
determining liability under the Securities Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
that is incorporated by reference in this Registration Statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
