The stars of Downton Abbey aren’t the only luminaries whom journalists will chat with during PBS’s portion of the Television Critics Association Summer Press Tour today and Wednesday. Other big names at the Beverly Hilton in Beverly Hills, Calif., include rapper and songwriter Nas, director Spike Lee, Oscar winner Geena Davis, actor Nathan Lane and television legend Dick Cavett. The twice-yearly tour is a chance for broadcasters to woo more than 200 reporters with news of their upcoming schedules, deploying sizzle reels, high-profile appearances, question-and-answer sessions and, of course, food and drinks. PBS President Paula Kerger will greet journalists during her executive session at 10 a.m.

New digital offerings from NPR and PBS aim to give public media additional platforms for building online audiences while gaining insights into how listeners and viewers interact with digital content. These digital initiatives — PBS’s Membership Video on Demand service and NPR’s long-awaited NPR One app — were demonstrated and discussed during the Public Media Development & Marketing Conference in Denver July 9-12. The frequent name-changes for NPR’s mobile app during its development — it has been variously referred to as “Project Carbon,” “Infinite Player” and “MPX” — prompted laughter among PMDMC attendees when recounted by Zach Brand, NPR’s v.p. of digital media.

A rejiggered phone booth from New York Public Radio, a mobile app produced by StoryCorps and a public-records data tool from the founder of FOIA Machine are among the 16 recipients of grants from this year’s Knight Foundation Prototype Fund. The foundation’s annual contest awards six-month, $35,000 grants to help recipients develop early-stage media ideas. Winners were announced Thursday. “While six months and a $35,000 grant might not always be enough to finish version one of a project, it can go a long way towards validating an assumption, developing a minimum viable product or identifying a need to revise an approach,” Chris Barr, a media innovation associate with Knight, wrote in a release.

NPR has stepped back from plans to curtail its ombudsman’s duties after receiving criticism from journalists and leaders of its member stations. The blowback began with a blog post by New York University journalism professor Jay Rosen, who pointed out Monday that a job posting for NPR’s next ombudsman specified that the in-house watchdog should refrain from “commentary” and “judgment.” Edward Schumacher-Matos, NPR’s current ombudsman, will end his three-year term in September. Rosen saw the change in language as an effort to defang the ombudsman, which he argued would remove a valuable check on NPR’s reporting. Some station leaders noted Rosen’s post and shared his concerns.

New York’s WNYC-FM has received a $1 million grant from the Robert Wood Johnson Foundation for a new reporting unit focused on health issues. The unit will cover healthy living and wellness, the policy and economics of health care, and medical science and discovery. WNYC will use the grant to hire reporters, producers, editors and audience-development specialists. Content created by the unit will be featured on WNYC’s The Brian Lehrer Show and the station’s local editions of Morning Edition and All Things Considered. The reporting will also be featured nationally on WNYC and Public Radio International’s The Takeaway and on American Public Media’s Marketplace.

Though the FCC’s incentive auction next year might give a short-term financial boost to a handful of public TV stations, it could erode the field’s ability to provide over-the-air signals to all of the nation’s homes, according to a new CPB white paper that outlines policy implications for local decision-makers. “Narrow financial calculations cannot measure the value of serving the educational needs of the nation’s children, providing trusted news, reliably delivering emergency alerts, presenting diverse viewpoints that would not otherwise be heard, and numerous other benefits provided today and in the future by the nation’s public media stations through over-the-air broadcasting,” says the report, “Facing the Spectrum Incentive Auction and Repacking Process,” released Thursday.

Maryland Public Television in Owings Mills promoted executives. Steven Schupak rises from s.v.p. and chief content officer to e.v.p. and chief operating officer at the Owings Mills station. George Beneman, chief technology officer, is now s.v.p. And Jay Parikh steps up to v.p. and head of MPT’s content division. “The promotions were due to the talents of these individuals coupled with restructuring to accommodate MPT’s fundraising campaign and Vietnam initiative,” said Larry Unger, MPT president, referring to a major event honoring veterans and their families that the state network is planning for April 2016.  “We are very excited for what the future has in store for MPT.”
