The biggest television networks have been firing on all cylinders this week, choosing what shows to renew, what new shows to add, and what titles would be executed via cancellation.

The busiest of the powerhouse networks have been ABC and NBC, who extended and killed off some big names in their lineups. The biggest of these was easily NBC’s Heroes, which people have expected to get canceled for a long time now, but it just kept on going. There were thoughts of bringing the show, which lost its appeal by the end of the second season, back for one more closing season. Instead, NBC decided to just end the show now, but they may still do one more special finale to wrap up whatever might need wrapping up in the world of Heroes. The network also ended Law & Order (but renewed spinoff SVU) and medical dramas Mercy and Trauma.

It’s been a bad, bad week for many fans of TV’s bountiful variety of shows. And since we don’t cover a whole lot of TV here at Geeks of Doom, aside from those we’ll pile it all into one mega-super-post.

The devastating week has left a veritable who’s who of ultra-popular titles dead in its wake, as shows like Fox’s 24, Scrubs, and The Hills have all been canceled. Rumors of their demise had been circulating for a while now, and it actually took confirmations from strange places to support the claims.
