I found this at Hispanic Business Magazine, online:
2005 Top 25 Hispanic Ad Agencies
December 2005, HISPANIC BUSINESS Magazine
Nowhere is the interface between English- and Spanish-language advertising more an issue than in the agency business. In 2002, 94.8 percent of billings reported by the Hispanic Business Top Hispanic Ad Agencies were for Spanish-language services. This year, the proportion has dropped to 81 percent.
A 2003 presentation by Aida Levitan, then-president of the Association of Hispanic Advertising Agencies, concluded that “AHAA agencies need to keep adapting and delivering solutions in the new environment. Crossover work (culturally relevant English advertising) is a great example of how AHAA agencies continue to deliver solutions to the market.”
Notably, even with the dilution, the total billings of the Top Hispanic Agencies list jumped a full 15 percent this year, from $1.276 billion in 2004 to $1.467 billion.
