                     CBS CORPORATION REPORTS RECORD RESULTS
                             FOR FOURTH QUARTER 1999

                                 REVENUES UP 24%
                                  EBITDA UP 85%
                           AFTER TAX CASH FLOW UP 81%
                        TELEVISION SEGMENT EBITDA UP 209%

        NEW YORK, February 15, 2000 -- CBS Corporation (NYSE: CBS) today
reported record revenues, EBITDA and after tax cash flow for the fourth quarter
of 1999.

        The Company's revenues for the fourth quarter climbed to a record $2,219
million, as compared to $1,791 million for the fourth quarter of 1998, an
increase of approximately 24%. EBITDA (earnings before interest, taxes,
depreciation and amortization, minority interests and equity losses) for the
fourth quarter of 1999 was $523 million, as compared to $282 million for the
fourth quarter a year ago, an increase of approximately 85%. After tax cash flow
(defined as income from continuing operations before New Media and equity
losses, and depreciation and amortization, as adjusted for the minority
interests) for the quarter grew to $279 million, as compared to $154 million for
the fourth quarter last year, an increase of 81%. As a result of the Company's
deferred tax position, after tax cash flow adjusted for cash taxes only was $332
million, an increase of $157 million or 90% from the fourth quarter of 1998.

        All of the Company's operating segments, except for the newly created
New Media segment, reported record fourth quarter results, led by CBS Television
and Infinity, which posted quarter-to-quarter revenue growth of 23% and 32%,
respectively. EBITDA for the Television segment was up a record 209%.

        "This was a great quarter, capping off a year where we produced record
growth in revenues, EBITDA and after tax cash flow," said Mel Karmazin,
President and Chief Executive Officer, CBS Corporation. "This growth was fueled
by our Television segment, which enjoyed substantial increases in the value of
its advertising time, and by our Infinity subsidiary, which posted double-digit
growth in every category. During the quarter, we completed the acquisition of
King World -- one of the premier names in television syndication. Also in the
quarter, Infinity completed its acquisition of Outdoor Systems, which
significantly expands our out-of-home position in the largest revenue markets.
Looking forward, we continue to be superbly positioned in all segments to profit
from a very robust advertising market."

        Television segment revenues during the quarter climbed to $1,331
million, an increase of approximately $248 million or 23%, reflecting pricing
increases and the inclusion of the results of King World. Excluding the impact
of King World, Television segment revenues increased by approximately $145
million, or 13%. EBITDA at the Television segment for the quarter increased by
approximately $136 million to $201 million, an increase of 209%, reflecting the
strong increases in 1999 revenue and the inclusion of the results of King World.
Excluding King World, Television segment EBITDA increased by approximately $108
million or 166%, versus last year's fourth quarter.

        Infinity's revenues also grew to record levels reaching $759 million for
the quarter -- an increase of $186 million, or 32% over the prior year period.
Infinity's dramatic growth reflects a 17% increase in radio revenues and a 90%
increase in outdoor advertising revenues. Excluding the newly acquired Outdoor
Systems, Infinity's revenue would have increased by approximately $113 million,
or 20%. EBITDA at Infinity also grew dramatically as a result of increased
revenues during 1999, climbing by $93 million to $350 million, an increase of
36%, for the quarter over the prior year period. Infinity's EBITDA growth
reflects increases of 22% at Infinity's radio operations and 180% at its outdoor
advertising operations. Excluding the impact of Outdoor Systems, same-station
EBITDA at Infinity grew by 23%.

         EBITDA at the Cable segment also increased during the quarter, up
approximately $34 million, or 121%. The Cable segment increase primarily
reflects operating gains at TNN, its country lifestyles cable network, and the
elimination of certain 1998 fourth quarter losses related to two cable networks
that were divested late in 1998. Excluding the impact of the two cable networks
divested last year and recovery of a previously written off receivable, the
Cable segment EBITDA increased by approximately $12 million, or 28%.

        The Company's newly created New Media segment incurred a loss of $30
million primarily as a result of a majority investment in iWon.com, which in the
fourth quarter launched an aggressive advertising and marketing plan. The
majority of these advertising and marketing costs were spent on the CBS and
Infinity media properties.

        The Company's net interest expense for the fourth quarter of 1999 was
$61 million, as compared to $98 million in 1998's fourth quarter, a decrease of
approximately 38%. This decrease was principally due to: lower debt levels as a
result of proceeds received from Infinity's initial public offering in late
1998; proceeds from business dispositions; cash received upon the closing of the
King World acquisition; and cash flow from operations offset in part by $1.8
billion in debt assumed upon the consummation of the Outdoor Systems
acquisition.

        Income taxes for the fourth quarter of 1999 were $159 million, as
compared to $27 million for the fourth quarter of 1998, an increase of $132
million. The increase is principally due to higher operating results.

        During the fourth quarter of 1999, the Company recognized its
proportionate share of losses for its Internet based equity investments, as well
as the related amortization expense. Together, these non-cash expenses totaled
$45 million after tax. The Company's non-cash losses reflect a continuing
investment in Internet based companies, which have aggressive start-up
advertising and marketing campaigns. These non-cash losses are expected to
increase as the Company adds to its strategic investments in Internet companies.

        The Company's income from continuing operations for the fourth quarter
of 1999 was $19 million, or $0.03 per diluted share, as compared to $3 million
for the fourth quarter of 1998, or $0.00 per diluted share, an increase of $16
million.

        The Company's reported net income for the quarter was $251 million, or
$0.34 per diluted share, as compared to a net loss for the year-ago quarter of
$1 million, or $0.00 per diluted share. The fourth quarter of 1999 includes a
$232 million after tax net gain on the disposal of certain discontinued
operations, or $0.31 per diluted share. This gain was due to the favorable
resolution of a number of contingencies related to the Company's disposal of its
former industrial businesses.

        Mr. Karmazin concluded: "We enter the year 2000 with excellent momentum
in all of our businesses, and eagerly anticipate the closing of our merger with
Viacom Inc., which was recently overwhelmingly approved by the shareholders of
both companies."


RESULTS FOR THE YEAR ENDED DECEMBER 31, 1999

        The Company's revenues from continuing operations for 1999 were $7,373
million, an increase of 8% over the prior year. Excluding the 1999 impact of
King World and Outdoor Systems, the 1998 Winter Olympics and including the
pro-forma effect of the American Radio Systems acquisition in the prior year,
revenues for the year ended December 31, 1999 increased by approximately 10%.

        The Company's EBITDA for 1999 increased by $540 million to $1,636
million, or 49% over the prior year. The Company's after tax cash flow for 1999
increased by $304 million to $863 million, or 54% over the prior year. As a
result of the Company's deferred tax position, after tax cash flow adjusted for
cash taxes only was $1,190 million, an increase of $503 million, or 73% from
1998. For the full year 1999, the Company reported income from continuing
operations of $157 million or $0.22 per diluted share, compared to a loss of $12
million, or $0.02 per diluted share, for the year 1998. Net income for the full
year 1999 totaled $780 million, or $1.08 per diluted share, compared to a loss
of $21 million, or $0.03 per diluted share for the year 1998. Net income during
1999 includes an after tax gain on disposal of discontinued operations of $628
million, or $0.87 per diluted share.
