SOURCES: Information for Agency Report 2012 came from questionnaires submitted by agencies and from additional analysis by Ad Age .

Most agencies submit revenue and other data on the questionnaire. Publicly held agency firms sometimes prefer not to reveal revenue for specific agencies, so figures for those agencies and some independent shops are based on Ad Age DataCenter estimates.

AGENCIES BY DISCIPLINES: Ad Age evaluates ad agencies and marketing-services agencies for breakout rankings by discipline. For these rankings, Ad Age applies a 75% rule:

If revenue from a particular discipline represents less than 75% of an agency's total revenue, only revenue attributed to that discipline is shown for that agency in the chart.

However, if the discipline accounts for 75% or more of an agency's total revenue—implying the discipline is the foundation of that agency—then an agency is ranked in that discipline at 100% of revenue.

ESTIMATES: An asterisk next to an agency name indicates Ad Age DataCenter estimate. Ad Age revised some 2010 estimates, mainly to reconcile revenue with agency, network or sector figures that agency firms disclose.

PRO FORMA RESULTS: Ad Age DataCenter reports revenue for agency networks and agencies on a pro forma basis where possible. Revenue shown for agency companies is revenue as stated by companies or, where indicated, Ad Age estimates. 2011 and 2010 revenue and rankings are based on data collected and/or adjusted in 2012, so the 2010 ranking for an agency company, network or agency may be different from the 2010 ranking that appeared in the April 2011 report (Agency Report 2011).

FOREIGN CURRENCIES: Ad Age converted 2011 revenue to dollars using 2011's average annual exchange rates and 2010 revenue to dollars using 2010's average annual exchange rates.
