I don't believe The Big Bang Theory has been cancelled. It remains in the top 10 scripted ratings and is still alive and well as for as I know. Yes, it is surprising though that a cerebral sitcom like this one would not be cancelled by now - Small miracles.
Go Mayim (Amy) go! I would have been proud having her (character) as a friend in college:)! The Big Bang Theory was promoting science (and its geeks)to mainstream America in a clever, funny and quite accurate way. No wonder it was cancelled. Look what is out there now? Maybe this is a sad reflection of what mainstream America is heading to? The move of TI is also clever! Two thumbs up for TI!
While I'm no big fan of mainstream television programming in general, I'll say that more shows like "Big Bang Theory" and (now-cancelled) "Numbers" will go a long way toward influencing the next generation of engineers.
This TI-Bialik partnership is a smart extension of that. (And all the more impressive because of her UCLA cred!).
