21% of the major agencies surveyed by Chicago-based Strata report they are "more focused on radio than they were a year ago." Strata says "TV is still tops for advertisers (41%), but the medium is steadily losing ground against digital (24%), with radio rounding out the top three advertising options at 13%." On a macro level, Strata says "optimism at the start of 2011 waned during the second quarter, with 17% of agency respondents noting a reduction in overall business, compared to a 38% jump in the first quarter." Radio's niche seems be that in this uncertain economy, it looks affordable, and Strata says "merging traditional and digital into one campaign is still a top concern for advertisers and their clients." Digital is growing: 76% of agencies surveyed say they're more interested now in Digital, even including the brand-new Google+, a rival to Facebook.
