Item 5.04.  Temporary Suspension of Trading Under Registrant’s Employee Benefit Plans.

On September 10, 2010, Liberty Media Corporation (the Corporation) delivered to its executive officers and directors (collectively, the Covered Persons) a notice under Rule 104 of Regulation BTR, pursuant to which the Corporation has imposed a “blackout” period in accordance with Section 306(a) of the Sarbanes-Oxley Act of 2002 (SOX) and the Securities and Exchange Commission regulations.

Because a blackout period has been imposed under the Corporation’s 401(k) Savings Plan (the Plan) beginning at 4:00 p.m., New York City time, on October 8, 2010, and ending on or about October 15, 2010, the Corporation is also imposing a SOX blackout period beginning at 4:00 p.m., New York City time, on October 8, 2010, and ending on or about October 15, 2010.  The blackout period under the Plan is needed in connection with the conversion of the Liberty Capital Group Stock Fund, the Liberty Interactive Group Stock Fund and the Liberty Starz Series A Common Stock Fund from unitized stock funds to “real-time traded” stock.

While the SOX blackout period is in effect, the Covered Persons (and their immediate family members who share their respective residences) should not, directly or indirectly, engage in any purchase, sale, transfer, acquisition, or disposition of any equity securities of the Corporation, including any series of common stock and any options.

The Corporation received notice of the Plan blackout required by the Employment Retirement Income Security Act of 1974 on September 8, 2010, and provided the SOX blackout notice to the Covered Persons prior to the fifth business day thereafter.

If the Covered Persons have any questions pertaining to the notice or the SOX blackout period, they were directed to contact Charles Tanabe, Pam Coe or Craig Troyer in the Legal Department of the Corporation by telephone at 720-875-5400 or by mail at 12300 Liberty Boulevard, Englewood, CO 80112.
