After speculation that NBC's breakout hit The Voice may land the post-Super Bowl slot in February, NBC made it official today. Given its midseason launch, the singing competition appeared the leading contender for the biggest annual series showcase. Additionally, unscripted series tend to do very well after the Super Bowl as proven by CBS' Survivor and Undercover Boss. Here is NBC's release:

UNIVERSAL CITY, Calif. (May 31, 2011) – NBC will broadcast a special hour-long episode of “The Voice” following the network’s exclusive coverage of Super Bowl XLVI on Sunday, February 5 (10-11 p.m. ET; time approximate). The announcements were made today by Bob Greenblatt, Chairman, NBC Entertainment.
