ITEM 8.01. OTHER EVENTS

     On July 21, 2005, Liberty Media Corporation ("Liberty") completed the spin
off (the "Spin Off") of its wholly-owned subsidiary, Discovery Holding Company
("DHC"), to its shareholders. At the time of the Spin Off, DHC assets were
comprised of Liberty's 100% ownership interest in Ascent Media Group, LLC,
Liberty's 50% ownership interest in Discovery Communications, Inc. and $200
million in cash. In connection with the Spin Off, holders of record of Liberty
common stock on July 15, 2005 (the "Record Date") received 0.10 of a share of
DHC Series A common stock for each share of Liberty Series A common stock owned
at 5:00 pm New York City time on the Record Date and 0.10 of a share of DHC
Series B common stock for each share of Liberty Series B common stock owned at
5:00 pm New York City time on the Record Date. The Spin Off is intended to
qualify as a tax-free spin off. As a result of the Spin Off, the financial 
statement balances and accounts of DHC are no longer included in the 
financial statements of Liberty. No gain or loss was recognized by Liberty in
connection with the Spin Off due to the pro rata nature of the distribution.

     In anticipation of the Spin Off, Liberty made certain changes to the
presentation of its operating segments included in its 2005 Quarterly Reports on
Form 10-Q. The purpose of this Form 8-K is to update Liberty's operating segment
disclosure and Management's Discussion and Analysis of Financial Condition and
results of Operations ("MD&A") that originally appeared in Liberty's December
31, 2004 Annual Report on Form 10-K to reflect these presentation changes. In
addition, Liberty's financial statements as of December 31, 2004 and 2003 and
for the three years then ended (the "2004 Financial Statements"), included in
its Annual Report on Form 10-K, and its financial statements as of (1) March 31,
2005 and for the three months then ended, (2) June 30, 2005 and for the six
months then ended and (3) September 30, 2005 and for the nine months then 
ended (collectively, the "2005 Financial Statements") included in its Quarterly
Reports on Form 10-Q may be incorporated by reference into certain registration
statements filed by Liberty in the future. Accordingly, Liberty is revising its
2004 Financial Statements and 2005 Financial Statements to retroactively 
present DHC as a discontinued operation and to reclassify cash flows from 
discontinued operations. The revised financial statements and MD& A are filed
herewith under Item 8.01 as Exhibits 99.1, 99.2, 99.3 and 99.4.
