From the folks at Deadline.com:
Discovery Channel’s Shark Week clocked its biggest audience in its 26-year history Sunday night. Nearly 5 million “fin-atics” (blame Discovery, not me) tuned in for the two-hour fake docu, Megalodon: The Monster Shark Lives – not all of them happily. Megalodon was up 141% in the 25-54 demo compared to the same two hours of 2012. Later, Shark After Dark, Shark Week’s first ever late-night talk show, clocked 2.1 million viewers. Discovery noted this afternoon that Shark Week continues to dominate social conversation year after year. On Sunday, it was responsible for the #1 most social show — Megalodon — across broadcast and cable, according to SocialGuide, beating the NFL Hall of Fame Game — and even Justin Bieber: Never Say Never! Shark Week conversation on Twitter grew 66%, year over year, in primetime and late night, and was responsible for nearly 1 million Tweets for the day.
