Shark Week 2015 snagged an average of 2.503 million viewers from July 5-12. That’s up 1% compared to last year’s orgy of Sharkness and trails only 2013’s 2.562 million Live + Same Day crowd, making it the the franchise’s second biggest primetime crowd on record for Discovery Channel.

More important for Discovery Channel, Shark Week copped the franchise’s highest rating in the its 28-year history in the network’s target demographic, adults 25-54. In that age bracket, the Sunday to Sunday programming block clocked a 1.46 rating in primetime.


This year’s most watched Shark Week show in overall audience was Wednesday night’s Super Predator, with its crowd of 3.355 million at 9 PM. In the network’s target 25-54 demo, this year’s best performing Shark Week show: Sunday, July 6’s Monster Mako at 10 PM with a 1.9 rating.

Surviving as Shark Week’s biggest overall draw ever: 2013’s Megalodon: The Monster Shark Lives which snared a whopping 4.8 million Live + Same Day viewers back on August 4 of that year, and a 2.6 rating in the target demo.  Discovery Channel got a lot of viewers, but also a lot of criticism, for that fake documentary, and current channel chief Rich Ross has vowed no fake stuff on his watch.

The week of July 6 stands as Discovery Channel’s most watched week on record with an average of 2.38 million viewers. That distinction formerly belonged to the Raising the Mammoth week back in 2000 when Discovery premiered its iconic special, on March 12, and climbed to an average audience of 2.35 million.

Ratings for this year’s Shark Week are coverage area data. Discovery Channel currently is available in 82.4% of the country (95.969 million homes out of 116.400 million Total U.S.). Last year at this time, Discovery Channel was in 84.3% of all U.S. homes (97.581 million out of 115.800 million).  Coverage area data, with fewer homes, cause rating to go up.
