For squeezed publishers, a bit of good and bad news: CPMs will rise more than 75% over the next five years. But overall growth of the online display advertising market will grow more slowly than expected, according to an estimate from Forrester.

Average CPMs -- the rate advertisers pay for 1,000 impressions -- will rise 76% to $4.68 by 2017 from $2.66 in 2012, according to a survey of 232 marketers conducted by the research firm.
