Pledge results reported by public TV stations from recently concluded on-air fundraisers were down 20 percent to 25 percent from the March 2012 drive, according to Kristen Kuebler, director of station research for Arizona-based TRAC Media. For most stations, the March fund drive is typically the biggest of the year, and revenues generated from it influence budgeting for the next fiscal year. Stations reported to TRAC and PBS that audience response to the latest pledge shows was tepid at best. The top-performing show among TRAC’s client stations was Magic Moments: The Best of ’50s Pop, a program that was first released for public TV broadcasts in 2005. It brought in 8 percent of all pledges, below their strongest show from the March 2012 drive: a self-help special from motivational speaker Wayne Dyer, Wishes Fulfilled, that generated 11 percent of total dollars raised by TRAC stations.
