This prospectus supplement supplements the prospectus dated August 23, 2006 of Liberty Media Corporation, relating to 3,073,232 shares of Liberty Interactive Series A common stock, par value $.01 per share, which may be sold from time to time by the selling stockholders named therein and in any prospectus supplement.  You should read this prospectus supplement in conjunction with the prospectus, and this prospectus supplement is qualified by reference to the prospectus, except to the extent that the information in this prospectus supplement supersedes the information contained in the prospectus.

Liberty Interactive Series A common stock is listed on the Nasdaq Global Select Market under the symbol “LINTA.”  On August 14, 2007, the closing sale price of Liberty Interactive Series A common stock on the Nasdaq was $19.04 per share.

Investing in our securities involves risks.  You should carefully consider the matters described under the caption “Risk Factors” beginning on page 1 of the prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if the prospectus or this prospectus supplement is truthful or complete.  Any representation to the contrary is a criminal offense.

The following table replaces in its entirety the selling stockholder table included in the prospectus (as it may have been supplemented from time to time) and sets forth information with respect to each selling stockholder, the number of shares of Liberty Interactive Series A common stock owned by such selling stockholder and the number of shares of Liberty Interactive Series A common stock owned by such selling stockholder that may be sold pursuant to the prospectus.  The shares of Liberty Interactive Interactive Series A common stock included in the table include shares issued at the time of the Merger and the shares issued in respect of the earnout payment.  Because each selling stockholder may sell all or some of such stockholder’s shares of Liberty Interactive Series A common stock from time to time under this prospectus and the selling stockholders may have sold some of such stockholder’s shares of Liberty Interactive Series A common stock prior to the date of this prospectus supplement, no estimate can be given at this time as to the number of shares of Liberty Interactive Series A common stock that will be held by a particular selling stockholder following any particular sale of Liberty Interactive Series A common stock by such selling stockholder.  Changes in the information concerning the selling stockholders will be set forth in supplements to the prospectus when and if necessary.  As of July 31, 2007, there were 602,175,656 shares of Liberty Interactive Series A common stock outstanding.
