The perennially quote-worthy cable satirists reached a new pinnacle of public influence with the 2010 Rally to Restore Sanity on the National Mall. The duo's plea for a new civility in our discourse got lots of laughs, but it became much more serious in the aftermath of the Tucson shooting, as renewed attention was paid to the extreme rhetoric being used in the political arena. Last September Colbert testified in front of Congress, appearing (albeit in character most of the time) before a House subcommittee on immigration. Stewart's Daily Show overtook Jay Leno and David Letterman in ratings among the 18-49 demographic for the first time ever during the fourth quarter of 2010.
