>I would rather the Tonys be on PBS as well. They're never going to get the ratings CBS wants.<
As much as I'm bothered by these categories not being presented in the national broadcast, moving the broadcast to PBS is not the answer either. Theatre is incredibly marginalized by national media, with little to no coverage, except for the biggest musicals or a Hollywood celebrity trying their luck on the stage. The Tony broadcast is one of the few opportunities the theatre industry has to market itself to a national audience, and again, I understand the need for entertainment over the categories that hold less interest to general viewers.
Although never a ratings champ, the Tonys stay on CBS for a variety of reasons: CBS president Les Moonves loves the theatre; the Tony Awards is watched by people who go to the theatre and have a higher median income, which attracts higher end advertisers; and the Tonys are usually a pretty solid awards show, and the broadcast tends to win Emmy Awards.
As much as PBS might produce the Tony Awards broadcast of our dreams, if you love the theatre, you should prefer for it to remain on national network TV where millions more will see it.
Begin at the beginning and go on till you come to the end: then stop.
