So, Which Shows Were No. 1 in 2010?

Glee, Walking Dead, Betty White, more: A look at the year's greatest ratings hits

Who was Glee's biggest guest star? Which Real Housewives bout knocked out the most viewers? And which vampire bite bit the deepest?

A look at 2010's greatest ratings hits:

• Glee topped out on April 13 with "Hell-O" (13.7 million viewers). The episode benefitted from Gwyneth Paltrow  Britney Spears Idina Menzel and Jonathan Groff—and an extremely helpful American Idol lead-in. 

• Glee's biggest episode not boosted by Idol was Sept. 28's Spears-boosted "Britney/Brittany" (13.5 million). 

• The Real Housewives franchise hit a new high (or low) with Aug. 30's New Jersey reunion shoving match (3.9 million).

• Jersey Shore hit a new high (or low) with Sept. 30's Snooki-Angelina disagreement brawl (6.7 million).

• In a twist, Keeping Up With the Kardashians set a new network record on Feb. 28 (4.8 million) without resorting to fisticuffs. (The episode was marked by the birth of Kourtney Kardashian's son, Mason.)

• Vampire Diaries was the top CW drama; the top Vampire Diaries was Feb. 4's "Children of the Damned" (4 million).

• True Blood was the top vampire show; the top True Blood was Aug. 29's "Fresh Blood" (5.4 million).

• Zombies topped vampires, thanks to The Walking Dead, which topped out with Dec. 5's season finale (6 million). 

• American Idol, which averaged 24.8 million for its Tuesday shows, topped everything.

• The Jan. 18 iCarly special, iSaved Your Life, was cable's No. 1 entertainment show (12.4 million).

• Saturday Night Live's biggest guest host was (who else?) Betty White (12.1 million on May 8).

• SNL's second-biggest guest host was (now, this is a bit unexpected…) Paul Rudd (7.6 million on Dec. 11).

• For the fall season through Dec. 5, the broadcast show that added, on average, the most DVR viewers after a week's worth of playback was Modern Family Grey's Anatomy Hawaii Five-O (3.2 million). Parenthood and Fringe grew their audiences by the biggest percentage.  

• The most-watched animated holiday special was Charlie Brown Christmas Rudolph the Red-Nosed Reindeer (12.2 million).
