The information contained in Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following information:

8

As previously reported, Liberty has from time to time considered increasing its equity interest in the Company.  In this regard, Liberty was approached by a large institutional stockholder of the Company regarding a purchase of a portion of such stockholder’s shares of Common Stock.  During the course of considering such purchase, Liberty learned from the Company that the Company intended to put in place certain restrictions that would discourage Liberty from acquiring additional shares of Common Stock.  On January 10, 2008, in order to enable it to complete its proposed purchase of additional shares, Liberty entered into a Standstill Agreement (“Standstill Agreement”) with the Company, pursuant to which Liberty agreed, on behalf of itself and its affiliates, subject to certain exceptions, not to acquire additional securities of the Company for a certain period of time and the Company agreed not to take certain action that would discourage Liberty from acquiring additional shares of Common Stock, including the proposed purchase of additional shares from the institutional investor as described in this Amendment.

Subject to any restrictions contained in the agreements attached as Exhibits to this Amendment or previously filed as exhibits to the Schedule 13D, Mr. Diller may purchase additional shares of Common Stock in the open market or in private transactions. Further, on termination of the Standstill Agreement, and depending on market conditions and other factors, the Reporting Persons (including Liberty) or their respective subsidiaries may also purchase additional shares of Common Stock in the open market or in private transactions.  Alternatively, depending on market conditions and other factors, and subject to any restrictions described in Items 5 or 6 or contained in the agreements attached as Exhibits to this Amendment or previously filed as exhibits to the Schedule 13D, the Reporting Persons or their respective subsidiaries may sell all or some of their shares of Common Stock (including, in the case of Liberty, (i) its interest in the BDTV Entities and (ii) in connection with certain hedging transactions it may engage in as described in Item 6 of the Schedule 13D, in each case, subject to certain specified limitations).

Subject to the foregoing and except as described in Items 5 and 6 or contained in the agreements attached as Exhibits to this Amendment or previously filed as exhibits to the Schedule 13D or as has been publicly announced by the Company, (i) Liberty does not have and, to the best of Liberty’s knowledge, none of its directors or officers have, any plans or proposals that relate to or would result in any of the actions set forth in clauses (a) through (j) of Item 4, and (ii) neither Barry Diller, nor any of the BDTV Entities, nor any of the directors or officers of any of the BDTV Entities, have any plans or proposals that relate to or would result in any of the actions set forth in clauses (a) through (j) of Item 4, except that, in the case of Mr. Diller, Mr. Diller may dispose of shares of Common Stock to satisfy the exercise price and tax withholding obligations in connection with the exercise of employee stock options.

The information contained in Items 5 and 6 of this Amendment is hereby incorporated by reference herein.

ITEM 5.                  Interest in Securities of the Issuer

The information contained in Item 5 of the Schedule 13D is hereby amended and supplemented by adding the following information:

On November 28, 2007, the Diller-Von Furstenberg Family Foundation, a private foundation as to which Mr. Diller disclaims beneficial ownership, sold in the open market 70,588 shares of Common Stock at a price of $27.63 per share.

On January 10, 2008, Liberty purchased 14,000,000 shares of Common Stock from an institutional investor for an aggregate purchase price of $339,500,000 in cash, or $24.25 per share. The aggregate amount payable by Liberty in connection with the foregoing purchase was drawn from the working capital of Liberty.

After giving effect to the foregoing transactions, the members of the Reporting Group beneficially own 66,202,229 shares of Common Stock and 25,599,998 shares of Class B Common Stock, which shares constitute 26.2% of the outstanding shares of Common Stock and 100% of the outstanding shares of Class B Common Stock.  Assuming the conversion of all of the Reporting Group’s shares of Class B Common Stock into Common Stock, the Reporting Group would beneficially own 33.0% of the outstanding Common Stock (calculated in accordance with Rule 13d-3).  Because each share of Class B Common Stock generally is entitled to ten votes per share, each share

9

of Common Stock is entitled to one vote per share and each share of outstanding preferred stock is entitled to two votes per share, the Reporting Persons may be deemed to beneficially own equity securities of the Company representing approximately 63.4% of the voting power of the Company.  The foregoing beneficial ownership amounts exclude shares of Common Stock beneficially owned by the executive officers and directors of Liberty and shares of Common Stock beneficially owned by Diane Von Furstenberg, Mr. Diller’s spouse, as to which Mr. Diller disclaims beneficial ownership.  The foregoing beneficial ownership amounts are based on 252,262,836 shares of Common Stock, 25,599,998 shares of Class B Common Stock and 758 shares of preferred stock outstanding, in each case, as of the close of business on December 31, 2007.(1)

The information contained in Item 6 of this Amendment is hereby incorporated by reference herein.

ITEM 6.                  Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

The information contained in Item 6 of the Schedule 13D is hereby amended and supplemented by adding the following information:

On January 10, 2008, Liberty and the Company entered into the Standstill Agreement.  The description of the Standstill Agreement set forth below does not purport to cover all the provisions of the Standstill Agreement, and is qualified in its entirety by reference to the Standstill Agreement, which is filed as Exhibit 57 hereto, which is incorporated into this Amendment by reference.

Pursuant to the Standstill Agreement, Liberty agreed, subject to certain exceptions (including an exception for the aforementioned purchase of 14,000,000 shares of Common Stock from an institutional investor), that it would not, and would not permit its affiliates to, acquire, or enter into any agreement, arrangement or understanding to acquire with any person other than the Company, additional securities of the Company.  The Standstill Agreement will terminate upon the first to occur of:

·      the day after the Company completes the proposed spin-offs announced in the Company’s November 5, 2007 press release;

·      the Company publicly announces the abandonment of such transactions or ceases to pursue in good faith consummation of such transactions;

·      April 15, 2009; and

·      subject to certain exceptions, if any person or group (as defined in Rule 13d-3 under the Exchange Act) (other than Liberty and Barry Diller) acquires beneficial ownership of equity securities of the Company in an amount exceeding 15% of the outstanding equity securities of the Company.

                The information contained in Item 5 of this Amendment is hereby incorporated by reference herein.

ITEM 7.                  Material to be Filed as Exhibits.

The information contained in Item 7 of the Schedule 13D is hereby amended and supplemented by adding the following information:

 (1) We have based our calculations of the ownership percentages on the number of outstanding shares of the Company obtained by reducing 6,000,000 from the number of outstanding shares of Common Stock as of December 31, 2007, which number was provided by the Company.
