WELL, CRAP: Just checked and it looks like the PBS Media Matters weblog episode isn’t airing in Knoxville. Bummer.
UPDATE: Oliver Willis informs me that it’s on here on Sunday the 19th at 7pm. I only checked the program guide for the 16th and 17th because the PBS folks told me it was going to be on the 16th. Let this be a lesson for you: check those local listings!
