It seems the heroic four-season run of a once-popular NBC series has come to an official end. The Live Feed is reporting that NBC has officially canceled Heroes.

It was said that the network was mulling over options for a shortened final season to give some closure to the remaining fans of the show, but it was ultimately decided that it wasn't worth it. However, Deadline Hollywood is reporting that NBC is, "working on a way to wrap up the show. That will be determined after the upfront." The site believes that could mean a possible two-hour or four-hour TV movie that will finalize the series. The network's upfront presentation is on Monday and we'll be sure to keep you posted on any further details on a Heroes TV movie.

Earlier today, The Live Feed also reported that NBC had canceled its two medical dramas - Trauma and Mercy. Both first-year shows had been struggling in ratings and Trauma had actually already been canceled once, until the network ordered more episodes to fill in for the 10 PM slot after the failed primetime experiment The Jay Leno Show came to an end.
