'The Big Bang Theory' renewed through 2017

"The Big Bang Theory" will be back (and back, and back): CBS just handed the series a three-year renewal notice that'll keep it on the schedule through 2017, or the hit's 10-year anniversary. 

“This multi-year deal further strengthens our network’s position for future seasons," said CBS Entertainment chief Nina Tassler in a statement. Indeed it does. "BBT" is TV's most watched comedy, and big hits like this don't roll around all that often anymore.
