This year's "Shark Week" on the Discovery channel broke all viewership records in the 26 year history of "Shark Week" on Sunday, Aug. 4, with the premiere of "Megalodon: The Monster Shark Lives," which had 4.8 million total viewers. 

The show was the highest rated and most watched "Shark Week" episode to date.  Additionally, "Megalodon" was up 141 percent in the 25-54-year-old demo versus the same time period in 2012.

However, despite the high viewership, hundreds of viewers were disgruntled about the fake documentary. The show snuck in a few quick disclaimers at the end that basically revealed their forgery, but many were angry about the deception.

Meanwhile, "Shark After Dark," "Shark Week's first-ever late-night talk show, had 2.1 million viewers. Hosted by comedian Josh Wolf with special guests that included actor Dominic Monaghan, "Shark After Dark" was up 62 percent in the 25-54-year-old demo versus last year's "Shark Week" Sunday 11 p.m. airing.

"Shark Week" conversation on Twitter grew 66 percent year over year in primetime and late night and was responsible for nearly 1 million Tweets for the day.
