What TV series boasts the most watched single episode this decade (since 2010) in the U.S.?

Amazingly, the most watched episode this decade was from the Undercover Boss series on February 7th, 2010. What escalated the number of viewers was not only the fact that it was its debut show, but that it immediately followed Super Bowl XLIV.

The show featured President and COO Larry O'Donnell of Waste Management, Inc. and was the most watched new series premiere since Dolly 22 years previously.

This wasn't the most watched post Super Bowl episode of all time though. Two shows that scored higher in that slot were a Friends special and Survivor.
