PORTLAND, Ore. — Addressing the nearly 500 attendees of the Public Radio Program Directors conference, NPR CEO Jarl Mohn reassured attendees Tuesday that he would renew the network’s focus on radio programming and challenged them to take part in a systemwide experiment to boost listening to NPR’s newsmagazines. “If we don’t get the radio part right, if we don’t get the terrestrial part right, if we don’t get broadcasting right, the rest of it isn’t going to make a difference,” Mohn told the crowd. “So you’re going to see from us, and from me, a renewed focus on the broadcasting side of the business.”

Public stations in Connecticut and San Mateo may be at the leading edge of a mass sell-off of public media assets in next year’s FCC spectrum auction. These stations have entered into agreements with LocusPoint Networks, a subsidiary of the private equity firm Blackstone Group, whereby LocusPoint shoulders the stations’ operating costs until the auction and then takes a significant share of the auction revenue after the station has sold its spectrum to wireless bidders. These deals have to be disclosed to the FCC, but their details do not. When the spectrum is auctioned, stations  may receive tens of millions of dollars for their spectrum, especially in congested coastal areas.

Two major donors and board members of Rochester, N.Y., dual licensee WXXI died Sept. 5 after their plane crashed in the ocean off the coast of Jamaica. Both were 68. Larry and Jane Glazer, major figures in Rochester’s business community who both served on WXXI’s board and co-chaired the station’s $17 million Go Public capital campaign, were flying their single-engine plane from Rochester to Naples, Fla., when their aircraft became unresponsive. Larry, a registered pilot, was at the controls. The North American Aerospace Defense Command, which shadowed the plane after the pilot became unresponsive, reported seeing the pilot slumped over and the windows frosted, usually a sign of decompression.

With the death of Joan Rivers, Jay Kernis, former senior v.p. for programming at NPR, shared this remembrance of Rivers on his Facebook page yesterday. It’s reproduced here with his permission. Between 2001-08, I was SVP for Programming at NPR and someone told Joan that she would be perfect to host a public radio show. I had interviewed her many years ago for NPR and I knew from producers like Amy Rosenblum just how smart Joan was. I was thrilled to be invited for lunch at her remarkable home on the East Side of NYC. Wore a suit, arrived ten minutes early with a notebook filled with Rivers research.

At least two public television networks opted not to air this week the POV documentary After Tiller, which profiles four late-term abortion providers and prompted a campaign among anti-abortion organizations. POV’s plans to air the film’s national broadcast premiere at 10 p.m. Sept. 1 spurred an Aug. 27 online statement from Judie Brown, president of the American Life League, who called the documentary “nothing short of pure propaganda intended to demonize the entire pro-life movement and drum up support for late-term abortion.” Several other anti-abortion websites urged visitors to contact PBS headquarters or PBS Ombudsman Michael Getler to protest stations airing the film.
