Speaking as a "fourth estater", I've been somewhat surprised with J! allowing Arthur Chu to participate in so many interviews while still champ. The show was a stickler for decades about contestants doing media interviews -- the show's unofficial policy always seemed to be "local media can chat with area contestant ahead of first appearance. Don't ask about how the contestant did or the interview ends." IIRC, Ken Jennings really didn't start doing interviews until J! hit the summer hiatus, when his winning streak was, I believe, 38.
With Arthur sitting out until February 24, and that game determining whether he gets a slot in the TOC, I can't blame J! for loosening up their media restrictions to go for ratings gold.
