Based on the ratings for last night’s Golden Globes, Tina Fey and Amy Poehler could probably sign a deal to host the show for life if they wanted. Sunday’s three-hour broadcast drew just under 21 million viewers, making it the most-watched Globes since 2004. Among viewers under 50, the show notched a 6.5 rating, its best performance since 2007. While ratings didn’t surge Sunday — last night’s event was up just one tenth of a ratings point in the demo and only 6 percent in viewers — they were still up dramatically (30 percent!) from 2012, before Fey and Poehler took over. The good news for NBC: While Amy and Tina aren’t locked in for life, they are signed on to return as hosts next January.
