“The Wanda Sykes Show” premieres tomorrow night at 11 on FOX. The big finale this week is “Mad Men” on Sunday at 10 on AMC. VH1′s “Tool Academy” finale is at 9, so get excited.

NUMB3RS might be getting the boot after six years.

CBS is making some mid-season changes. It is cutting the season order of “NUMB3RS” to 16 episodes, down from 22. This is in order to make room for shows like the reality “Undercover Boss” and the dramas “Miami Trauma,” “Flashpoint,” and “The Bridge.” Numbers gets cut short in its sixth season.

The fate of “The Oprah Winfrey Show” is up in the air. One report has it that Oprah will switch from broadcast to cable when her contract with CBS expires in 2011. Oprah would then be tree to move to her own cable network, which launches next fall. But CBS says they know nothing of any moves the talk-show diva is looking to make.

Also on the topic of talk shows, NBC has renewed “Maury,” “Springer,” and “Steve Wilkos” for at least three more years. Tribune, the company that syndicates these shows, also announced that some of its other shows, including “People’s Court,” “Judge Matis,” “TMZ,” “This Old House” and “Judge Jeanine Pirro” are renewed through 2012.

Scipps is purchasing a 65 percent majority stake in the Travel Channel from Cox Communications, pouring millions of dollars into the 22-year-old cable network and securing its near billion-dollar debt.

Comedy Central is teaming up with The Onion to produce a 30-minute television series inspired by The Onion Sports Network.

Finally this week, FX has a Western drama series under construction called “Reconstruction,” set in Missouri during the post-Civil War era.

Two of cable’s heavy hitters premiere tonight. Discovery Channel starts a new season of “Mythbusters” at 9 p.m., and Comedy Central has “South Park” at 10. Comedy Central also has “Secret Girlfriend’” at 10:30.

Investigation Discovery (for those of you who have it) has “The Bureau” about the FBI’s top cases, starting up at 9 p.m.

CBS will renew “Flashpoint” for at least 13 more episodes later this season. The Canadian import about a police “Strategic Response Unit” has been a rating success so far.

Bravo is expanding its “Real Housewives” brand with “The Real Housewives of D.C.” The cable network also renewed “New Jersey” for a second season.

“Curb Your Enthusiasm” had its best numbers in five on-and-off years on Sunday night, with 1.6 million total viewers at 10 p.m. for the “Seinfeld” reunion.

But the biggest news so far is this: “Monday Night Football” with the Vikings versus Packers gave ESPN the largest audience in the history of cable television and ESPN’s own best ranking in its history, attracting a 15.3 rating, or 21.8 million total viewers. It’s just a ridiculous number, as Brett Favre facing his old team boosted the game to a whole new level.
