The agency business has come back to life, with U.S. revenue jumping 7.7% as the domestic market led a 2010 worldwide rebound in advertising and marketing services.
The standout performer: digital marketing, which accounted for 28% of U.S. agency revenue.
Plot line of this recovery: The recession officially ended in June 2009, U.S. measured-media spending turned northward in first-quarter 2010 (according to WPP's Kantar Media), and U.S. advertising and marketing-services firms have added 23,100 jobs since ad industry employment hit bottom in February 2010 (according to Bureau of Labor Statistics data).
The Big Four agency holding companies -- WPP, Omnicom Group, Publicis Groupe, Interpublic Group of Cos. -- in 2010 added 11,000 jobs (including acquisitions) after slashing 22,000 jobs in 2009.

Shares in WPP, Omnicom and Interpublic in first-quarter 2011 reached their highest levels since pre-recession 2007, a sign of investors' optimism about the sector. Publicis shares this year reached their highest point since 2000.
U.S. 2010 revenue for marketing-communications agencies -- including advertising, marketing services, media, health care and public relations -- rose 7.7% to $30.4 billion, according to the Ad Age Agency Report, which tracked the performance of more than 900 U.S. agencies. (Ad Age DataCenter adjusted agency revenue figures for acquisitions to show revenue growth on an apples-to-apples basis.)
Every major agency discipline rebounded last year, with U.S. revenue growth in the range of 6% to 7% for most disciplines (including advertising, promotion, health care and public relations). Revenue for digital-specialty agencies (essentially digital pure-play agencies) surged 16.3%.
The U.S. was the world's star performer in 2010 for advertising and marketing services, exceeding expectations and outpacing growth in most other regions.
To be sure, some of the U.S. advertising market's recovery reflected what WPP Chief Executive Martin Sorrell has called a "dead cat bounce": The ad business fell so sharply that it wasn't surprising to see decent percentage gains when the economy began to recover after the longest recession (December 2007 through June 2009) since the Great Depression.

Remember how bad things were: U.S. ad spending as a percent of gross domestic product in 2009 slumped to its lowest level in decades, and U.S. agencies in 2009 saw the sharpest revenue drop (7.5%) since Ad Age began the Agency Report in 1945.
Ad spending and employment remain well off their peak. Publicis' ZenithOptimedia says U.S. ad/marketing-services spending won't break its 2007 record until 2013. U.S. ad and marketing-services firms employ 76,500 fewer people today than at the industry's pre-recession, late-2007 peak. (See AdAge.com/adjobs.)
But there is no denying the turnabout in ad spending last year as key advertising sectors including automotive rebounded from their Great Recession lows.
Omnicom in 2010 reported 8.7% U.S. organic growth (revenue growth after factoring out acquisitions/divestitures and the impact of foreign exchange), beating its 6.4% worldwide organic growth.
In 2010, Interpublic reported robust 10.1% organic revenue growth in the U.S., and Publicis posted 9.9% organic growth in North America, better in both cases than any other single region except Latin America.

Revenue for the world's 50 largest agency companies totaled $62.2 billion in 2010, up 9.4%. U.S. revenue for those firms jumped 11.4%. (Ad Age DataCenter did not adjust agency company total-revenue figures, so the high growth rates last year in part reflect acquisitions.)
The U.S. accounted for 42% of the top 50 agency firms' worldwide revenue.
With the economy and financial markets back on track, marketing-communications companies have returned to merger-and-acquisition mode, doing a lot of buying -- and some selling.
Omnicom is undertaking a global review of operations with the aim to reorganize or dispose of what President-CEO John Wren has termed "non-core, low-growth, low-margin businesses ... generally in smaller markets." As of April 2011, Omnicom had disposed of units with combined annual revenue of about $120 million.
