You have to love ABC! They have no compunction about putting out a press release about having a last place show and even manage to put some smile on it. The smile is they are closing the gap with Letterman vs. last year.
I do love ABC for publishing the data though and of course, Boston Legal (and ok, ok, Grey's Anatomy and Dancing with the Stars). I have not watched any of the shows below regularly in 10 years, but that's just because I'm old.
