Grand prize is $5,000 cash, second prize is $1,000 and third prize is "a total HD Radio upgrade for car, home and on the go." iBiquity's Senior VP of Broadcast Programs and Advanced Services Joe D'Angelo says "HD-2/HD-3 channels are becoming increasingly prevalent in the ratings, and now is the time to market the unique benefits they offer to advertisers." Here's what Ibiquity is looking for: campaigns that include NTR events, campaigns exclusive on an HD multicast channel, or campaigns that combine on-air/website and HD Radio. Deadline is August 15, with prize winners to be announced at the NAB/RAB Radio Show in Chicago in September. More info at the HD Radio Alliance website, here.
