FOR IMMEDIATE RELEASE
APRIL 17, 2006


                LIBERTY MEDIA CORPORATION ANNOUNCES 2006 GUIDANCE

Englewood, CO - As previously announced and subject to shareholder approval,
Liberty Media Corporation (NYSE:L; LMC.B) ("Liberty") intends to create two new
tracking stocks, one to reflect the performance of the assets and businesses
attributed to the Liberty Interactive Group and one to reflect the performance
of assets and businesses attributed to the Liberty Capital Group. Liberty
announced today the following 2006 outlook for the Liberty Interactive Group,
which includes QVC, its largest attributed operating business. In addition,
guidance is provided for Starz Entertainment Group, Liberty Capital Group's
largest attributed operating business.

LIBERTY INTERACTIVE GROUP

2006 GUIDANCE

Liberty expects the operations attributed to the Liberty Interactive Group,
which includes QVC for all of 2006 and Provide Commerce from the date of its
acquisition on February 9, 2006, to increase over the attributed 2005 operating
results, which included only QVC's operations, as follows:

     o    Revenue growth in the low double digits %.

     o    Operating cash flow (OCF) growth in low double digits %. *

     o    Operating income growth in low double digits %.

- ------------
* See : "Non--GAAP Financial Measures" for Liberty's definition of "Operating
Cash Flow" and why management believes estimated OCF is meaningful to investors.

<Page>

The foregoing estimates assume with respect to QVC, among other factors, that
its product mix and foreign currency exchange rates affecting its international
businesses will be consistent as compared to 2005, while revenue growth rates
will experience a slight slowing due to difficult comparisons to the favorable
results achieved in 2005. These estimated growth rates are not expected to be
achieved ratably on a quarterly basis as the Liberty Interactive Group's
attributed businesses will likely experience different quarter over quarter
growth rates for each calendar quarter of 2006.

Liberty is currently compiling its financial results for the first quarter of
2006 and expects to make those results publicly available on or about May 8,
2006. On a preliminary basis, Liberty expects that the attributed revenue growth
of the Liberty Interactive Group for the first quarter will be in the mid single
digits % and both the OCF and operating income growth will be in the high single
digits % . These results are attributable to sales performance that was slightly
below expectations for the quarter and negative exchange rate comparisons to the
first quarter of 2005 related to the international businesses. On a constant
dollar basis the expected growth rates for the quarter are in line with the
above stated full year guidance.


LONG-TERM OUTLOOK

Liberty expects that the combined compound annual growth rate in revenue and OCF
for the Liberty Interactive Group's attributed operating businesses over the
next five years, including the effects of potential acquisitions and assuming
constant foreign exchange rates, will be in the low double digits %.

LIBERTY CAPITAL GROUP

Liberty is not providing combined guidance for the businesses attributed to the
Liberty Capital Group for 2006 as such information is not considered meaningful
at this time. Guidance is being provided separately for Starz Entertainment
Group which is the largest operating business attributed to the Liberty Capital
Group.

STARZ ENTERTAINMENT GROUP-2006 GUIDANCE

Liberty expects that revenue, OCF and operating income of Starz Entertainment
Group ("SEG") for 2006 will be substantially similar to those recognized in
2005. This expectation is premised upon, among other factors, that SEG continues
to experience positive trends under its affiliation agreements, SEG's
distributors continue to see growth in digital subscribers consistent with that
experienced in 2005, the quantity and timing of receipt of output product from
the studios does not materially change from that experienced in 2005 and Starz
subscription units continue to increase. These estimates further assume that
SEG's 2006 programming costs increase by mid-single digit percentages over the
same periods in 2005.

NON-GAAP FINANCIAL MEASURES

This press release includes an estimate of the anticipated percentage change in
2006 operating cash flow compared to 2005 operating cash flow for the Liberty
Interactive Group and SEG. Liberty defines operating cash flow, which is a
non-GAAP financial measure, as revenue less cost of sales, operating expenses,
and selling, general and administrative expenses (excluding stock compensation).
Operating cash flow, as defined by Liberty, excludes depreciation, amortization,
stock compensation and other non-cash charges taken into account in computing
operating income in accordance with GAAP.

Liberty's management uses revenue and operating cash flow as a measure of
operating performance and for purposes of making decisions about allocating
resources to its subsidiaries and affiliates. Liberty's management believes the
presentation of the estimated percentage changes in operating cash flow is
helpful information to investors as it provides insight into management's
expectation regarding operating performance during the coming year. Because
operating cash flow is used as a measure of operating performance, Liberty views
operating income as the most directly comparable GAAP measure. Operating cash
flow is not meant to replace or supersede operating income or any other GAAP
measure. No reconciliation of estimated operating cash flow for 2006 to
estimated operating income for the same year is presented because these
estimated operating metrics are presented in broad ranges of possible outcomes
which do not lend itself to meaningful reconciliation.
