The Big Bang Theory keeps earning it’s status as the most successful comedy on TV: Thursday night’s airing delivered the show’s biggest 8 p.m. audience ever — 20 million viewers and a 5.6 rating among adults 18-49, blowing away everything else on the dial and helping pump up the rest of CBS’ line-up. (There was one Big Bang Theory special telecast at 8:30 p.m. on the show’s premiere night back in September that was slightly higher — otherwise this would be an unqualified Big Bang record).In fact, every CBS show was up over last week, starting with Big Bang up 4 percent, The Millers up 18 percent to its biggest audience yet, Crazy Ones up 20 percent, Two and a Half Men was up 9 percent and Elementary was up 11 percent.

Still, NBC had some uplift, with Community up 8 percent, Parks up 40 percent, and both Sean Saves the World and Michael J. Fox Show up 25 percent — but you can see for yourself below the spread between the Peacock and CBS:
