For one thing, it doesn't claim to be a "museum" anymore, thanks to Pat Mitchell, former PBS c.e.o. and current head of the recently renamed Paley Center for Media. Mitchell left PBS last year to lead the institution known as the Museum of Television and Radio until Mitchell changed its name, Newsday reports. She made the switch because she wants the center to embrace online media as well. Mitchell told the paper she left PBS because she was exhausted by the demands of the job.
