                             GREY GLOBAL GROUP INC.
                      REPORTS STRONG THIRD QUARTER RESULTS

New York,  New York - November 5, 2004--Grey  Global Group Inc.  (NASDAQ:
GREY) today  announced its results for the third quarter of 2004.

RESULTS
- -------

Revenue
- -------
Revenue for the third quarter was $358.0 million, an increase of 10.3% ($33.5
million) from the same quarter in 2003. For the nine months ended September 30,
2004, revenue was up $123.8 million, an increase of 13.1%. Revenue improved at
both the Company's non-North American ("international") and North American
operations. The increase was due, in part, to the continuing impact of a weaker
dollar; on a constant currency basis, revenue was up 6.2% for the quarter and
6.6% for the nine months ended September 30, 2004. Revenue for the North
American operations increased by 3.4% for the quarter and 7.1% for the nine
months, with exchange rate movements having only a marginal impact.
International operations reported a revenue increase of 16.1% for the quarter;
absent the effect of the exchange rate movements, international revenue would
have been up 8.6%. For the nine months ended September 30, 2004, international
revenue increased 18.0% (6.6% absent exchange rate increases).

Income of Consolidated Companies before Taxes on Income ("pre-tax profit")
- --------------------------------------------------------------------------
The Company reported pre-tax profit grew by 74.4% ($9.4 million) for the third
quarter when compared to the corresponding quarter in 2003 and 69.4% ($24.8
million) for the nine months ended September 30, 2004. In the third quarter, the
Company recognized $2.5 million of expenses in connection with the previously
announced signing of an agreement to have the Company merge into WPP Group plc.
and a loss of $1.8 million on the sale of its majority interest in APCO
Worldwide Inc., part of the Company's public relations/affairs operations. Even
after these charges, the Company's margins improved significantly. Comparisons
to 2003 third quarter results are also affected by the absence of a $2.6 million
reserve recorded last year in connection with the liquidation of a business in
Europe.

Net Income/EPS
- --------------
Net income was $10.3 million for the third quarter of 2004 and $27.4 million for
the nine months ended September 30, 2004 compared with $4.6 million and $14.4
million for the corresponding periods in 2003.

Basic and diluted earnings per common share for the three months ended September
30, 2004 were $7.50 and $7.26, respectively, compared to $3.57 and $3.28 for the
same quarter in 2003. Basic and diluted earnings were $20.05 and $19.44,
respectively, for the nine months ended September 30, 2004 versus $10.30 and
$9.45 in 2003.
