FOR IMMEDIATE RELEASE:
AUGUST 10, 2001

                                 [LIBERTY LOGO]

                       LIBERTY MEDIA CORPORATION ANNOUNCES
                            SPLIT OFF FROM AT&T CORP.

                    BEGINS TRADING ON NEW YORK STOCK EXCHANGE
                        UNDER THE SYMBOLS LMC.A AND LMC.B


ENGLEWOOD, CO - Liberty Media Corporation (NYSE: LMC.A and LMC.B) today
announced that it has successfully completed its split off from AT&T Corp. and
has begun trading as an independent publicly-traded company.

In the split off, each share of Class A and Class B Liberty Media tracking stock
was redeemed for one share of Liberty Media Corporation's Series A and Series B
common stock, respectively.

Liberty Media was acquired by AT&T through AT&T's acquisition of
Tele-Communications, Inc. in March 1999. The split off is intended to better
enable Liberty Media to raise capital on its own, use its stock as currency in
acquiring, merging or partnering with other companies and help the public
markets to better value the company. The action will also eliminate regulatory
and competitive conflicts of interest between Liberty Media and AT&T. As
previously announced, the Internal Revenue Service has ruled that the redemption
of the tracking stock and the split off qualify as tax-free for federal income
tax purposes.

Liberty Media holds interests in a broad range of Domestic and International
video programming, communications, technology and Internet businesses. Liberty
Media's principal assets include interests in Starz Encore Group LLC, Discovery
Communications, Inc., AOL Time Warner Inc., QVC, Inc., USA Networks, Inc.,
Telewest Communications plc, Gemstar-TV Guide International, Inc., Motorola,
Inc., Sprint PCS Group and The News Corporation Limited.
