undercover boss renewed 'Undercover Boss,' 'Amazing Race' renewed; 'Shameless' finale hits a series highToday’s TV snacks include reality-show renewals, ratings records for a couple of cable shows and an expansion of the college-football universe.

CBS has picked up both its Sunday reality shows, “Undercover Boss” and “The Amazing Race,” for the 2011-12 season. One caveat, though: As of now, the network has only ordered one cycle of “TAR,” which will be the 19th for the show. “Undercover Boss” is getting its third season. [CBS]

The season finale of “Shameless” on Showtime Sunday (March 27) set a ratings record for the series. The episode delivered 1.16 million viewers — the best for a first-season finale on Showtime in almost 10 years — in its first airing and a little over 1.5 million for the night. “Californication’s” finale drew 1.06 million viewers over three airings on Sunday.

Speaking of ratings records: Lifetime’s “Army Wives” also set series highs Sunday in viewers (4.8 million) and women over 18 (3.4 million), along with a season high in women 18-49 (2.2 million). [Lifetime]

College football fans will have one more place to watch games in the fall. As part of existing deals with Fox Sports, FX will carry at least 13 games featuring Big 12, Pac-12 and Conference USA teams. It’s the first time FX has carried college football since the late 1990s. [Deadline]

Discovery Channel has picked up a pair of shows highlighting “American sub-cultures” to air this summer. “Moonshiners” will follow, you guessed it, people who make moonshine in Appalachia, while “Mountain Men of Alaska” — starring singer Jewel‘s dad, Atz Kilcher, will spotlight his family and their life off the grid. Camera crews excluded, presumably. [Discovery]
