The broadcast networks are officially done with their upfront commitments as ABC, which had been holding out in a standoff with ad agencies, has closed the upfront book. The network is not commenting, but sources indicate ABC landed CPM increases of 7%-8% for a volume that is on par (or slightly below) last year’s $2.3 billion. The company is expected to provide more detail on its upfront performance during the Disney earnings call next Tuesday. Overall, it has been a challenging upfront market for the broadcast networks amid an across-the-board live viewing ratings erosion. NBC is the only network to lock in double-digit volume increases as the net continues its rebound after a couple of down years.
