Raymond Davis, a veteran broadcaster who influenced and nurtured the bluegrass music scene as a music host for WAMU in Washington, D.C., died Dec. 3 of leukemia. He was 81. Davis capped his 65-year career in radio broadcasting as an afternoon host on WAMU’s all-music station Bluegrass Country. He joined the pubcaster in 1985, when the station split its weekday format between NPR News programs and bluegrass, and retired in 2013. Davis started in radio at age 15 with a job at WDOV-AM in Dover, Del., according to a tribute page on WAMU’s website. He spent 38 years at WBMD in Baltimore, where he hosted live broadcasts from Johnny’s Used Cars.

Michael Riley, a former head of ABC Family, is the new president of Los Angeles-based KCETLink, the independent public media station and satellite TV channel. Riley succeeds Al Jerome, the KCET executive who led what had been PBS’s flagship station in Los Angeles through its acrimonious 2011 split from PBS. He spearheaded the station’s subsequent merger with noncommercial satellite broadcaster Link TV in October 2012. Dick Cook, board chair for KCETLink Media Group, cited Riley’s “strong track record in brand-defining content creation, strategic partnerships, acquisitions and digital leadership — both domestically and across international markets” in Monday’s announcement. Riley began in the job immediately.

New York’s WNET is reversing its decision — at least temporarily — to shift independent documentaries from primetime on its main channel to the secondary WLIW on Long Island, which reaches a far smaller audience.

The FCC is considering giving public radio stations at least two additional years — and maybe even a complete exemption — from a proposed agency regulation that could soon require other radio stations to start publishing public file records online, the agency said in a recent notice. “We recognize that some radio stations may face financial or other obstacles that could make the transition to an online public file more difficult,” said the FCC, in a notice of proposed rulemaking released December 18. “Accordingly, we believe that it is reasonable to commence the transition to an online public file for radio with stations with more resources while delaying, for some period of time, all mandatory online public file requirements for other stations.”

WKAR-TV in East Lansing, Mich., will make content from a weekly state politics and public affairs show available via a mobile app funded by a grant from the Investigative News Network. The scope of WKAR’s proposed app helped it stand out among a pool of 48 applicants, said Kevin Davis, c.e.o. and executive director of INN. “What made it unique was that the app was focused more on a program rather than on general content,” Davis said. “It was quite niche.” (Disclosure: Current is contracting with INN for web development services.) The weekly show, Off the Record, has provided coverage of Michigan affairs for 43 years, aided in part by WKAR’s location near the state capital.
