Information for Agency Report 2014 came from questionnaires submitted by agencies and from analysis by Ad Age DataCenter. To see the questionnaire, go to

Most agencies submit revenue and data via the questionnaire. Publicly held agency firms sometimes prefer not to reveal revenue for specific agencies; figures for those agencies and some independent agencies are Ad Age estimates. An asterisk next to an agency name indicates an Ad Age DataCenter revenue estimate.

Revenue and rankings for 2013 and 2012 are based on data collected and/or adjusted in 2014, so the 2012 ranking for an agency company, agency network or agency may be different from the 2012 ranking that appeared in the April 2013 report (Agency Report 2013).

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.

Questionnaires for Agency Report 2015 will be available in January 2015 at Agencies that want to receive a questionnaire for 2015's report may email .
