Hispanic- Total Hispanic television ad expenditures, growing about 25 percent a year, are estimated this year to come in north of $3.5 billion. The lion’s share, as usual, will go to Spanish- language TV. “We are targeting one of the biggest under-served markets in the nation,” says Rob Rose, a 15-year TV industry veteran when he founded Artist and Idea Management in February 2000—the same month that he left his job at Univision. Rose says that ad revenues for the English-language Hispanic market is expected to reach only about $500 million by 2010.
