“Impact” is a feel-good media buzzword of the moment, increasingly required by the funders of many projects and invoked by some PTV stations, news organizations and documentary producers as key to demonstrating the social good derived from their work. But defining the concept and then measuring whether a media project has demonstrated its value remain elusive challenges for many. During “Understanding Impact,” a two-day symposium convened last month at American University in Washington, D.C., participants explored a number of the ad hoc systems for tracking impact that are taking form. Organizations including the Center for Investigative Reporting in Emeryville, Calif., and KETC, the Nine Network of St.

A request by a Canadian college radio station to mount a 100-watt repeater in Montreal has triggered stiff opposition from Vermont Public Radio, whose coverage in the market would suffer interference if the signal were approved. The Concordia Student Broadcasting Corporation, a nonprofit connected to Montreal’s Concordia University, operates CJLO 1690 AM. An area near one of Concordia’s campuses receives the AM signal infrequently if at all. An engineer looked for room on Montreal’s crowded FM band to accommodate a 100-watt repeater, which would fill the hole in the AM signal. The proposed signal, 107.9 FM, is also used by VPR’s Burlington station, about 100 miles away.

CPB’s Inspector General has recommended that the corporation sanction Vermont Public Television in response to 22 open-meeting violations by VPT’s board dating from July 2011. In the May 5 report, IG Mary Mitchelson said that while 17 of the meetings were closed for appropriate reasons, such as personnel matters, the station failed to provide written explanations for why the meetings were not open to the public. The IG’s conclusions were based on interviews of board members who attended the meetings in question as well as an examination of documents detailing what business was transacted, the report said. Following the IG’s recommendation, the decision on whether or how to penalize the station rests with CPB’s management.

In a channel-sharing agreement announced Tuesday, Georgia Public Broadcasting will expand its public radio service into the Atlanta market starting June 1 via Georgia State University’s 88.5 WRAS-FM. GPB Radio will program the station with a news format from 5 a.m. to 7 p.m., providing Atlanta with its first public radio outlet to air news in midday hours. The city’s WABE, operated by Atlanta’s public school system, airs NPR’s newsmagazines but also schedules classical music from 9 a.m. to 3 p.m. weekdays. “We wanted to bring something that is not currently in the market,” said Bert Huffman, v.p. of development for GPB.

The Chicago network cited rising costs of satellite carriage and a desire to expand internationally as reasons for the move.

Public television stations are hoping that special access to a rich library of PBS programs will convince viewers to become members and entice members to keep contributing. The multiplatform subscription program, with the working title MVOD (Membership Video on Demand), will be built atop COVE, PBS’s local-national video site. PBS is backing the initiative with $1.5 million in its fiscal 2015 budget. MVOD will feature past seasons of signature PBS general-audience series and provide stations with the ability to add locally produced series, said Ira Rubenstein, head of PBS Digital. “I think of it as Amazon Prime or Netflix, but only for station members,” he said.

Death, Sex & Money, The Sporkful and The Longest Shortest Time join the station's digital programming lineup.

Los Angeles public TV station KCET is bringing back weekly series SoCal Connected after a yearlong hiatus, this time as a mix of hard news and features. The award-winning show will start its sixth season May 14. In previous seasons, SoCal earned a reputation for hard-nosed journalism, along with 17 local Emmys, by covering corruption at the Los Angeles Housing Authority, sweetheart deals involving electronic billboards and the dire consequences of climate change. But after the station dropped its PBS affiliation, it went into an economic tailspin that resulted in the layoffs of 22 employees, including Bret Marcus, SoCal’s executive producer.
