All the tube news that’s fit to surf …

– Betty White, Tom Selleck, and now Don Johnson is headed back to primetime, making it seem like 1985 in fall pilot action.

– As much as I loved this week’s episode of Lost – it was the perfect antidote, being one of the best episodes ever of the show, to Tuesday night’s American Idol performance installment, which was, hands down, the worst episode ever of AI – the Movieline.com snarky episode recap is almost as fun as the episode itself.

– At the Movies has been canceled. Let’s be honest, it was never the same without Siskel and Ebert‘s thumbs.

– Also dunzo: The Hills, after season six, which premieres on April 27.

– And Fox has put ‘Til Death out of its (and viewers’) misery, while Scrubs is also likely to be canceled.

– Endings is becoming a theme this week: Katherine Heigl has confirmed she’s quitting (actually, has already quit) Grey’s Anatomy.

– One more: Lost producers have revealed the title of the show’s series finale. It’s “The End.”

– The New York Jets’ training camp will be the subject of next season’s edition of HBO’s Hard Knocks.

– It may not be the savviest career move, but it’s still refreshing that even Big Love star Chloe Sevigny admits the just-concluded fourth season of her HBO show was, as she says, “awful.” It was especially bad in comparison to how great the show was in season three.

– CBS is launching its own reality dance series (because that’s definitely what’s missing in primetime), and Paula Abdul is said to top the network’s wish list of judges for the new show.

– Bill Cosby has made some very kind comments about his I Spy co-star Robert Culp, who died on Tuesday.

– Those infamous White House party crashers have landed on TV, as the wife, Michaele Salahi, will be one of Bravo’s Real Housewives of D.C.

– The Office has been hit-and-miss this season. The Jim/Pam baby episode has definitely been the highlight so far, along with the increased screen time for Craig Robinson since his Darryl got promoted. The comedian, whose Hot Tub Time Machine hits movie theaters today and who’ll host NBC’s Last Comic Standing this summer, says we’ll continue to see more and more of Darryl – the sharpest and most down to earth character at Dunder Mifflin – throughout the rest of the season.

– Diddy, whose name is among the dozens of people who’ve been mentioned as possible Simon Cowell replacements on American Idol, will perform on next Wednesday’s AI results show.

– And not only will we get a Madonna-themed episode of Glee on April 20, but a CD called The Power of Madonna, featuring seven Material Girl tunes performed by the Glee cast, will also hit stores and iTunes that day.
