NEW YORK (July 28, 2023) - "Shark Week," Discovery Channel's week-long celebration of sharks, hosted by Jason Momoa, returned for a landmark 35th year on Sunday, July 23 at 8pmET and drove the network to rank #1 in primetime for all of television with Adults and Men 18-49 and #1 across cable television with Adults and Men 25-54, Adults and Men 18-49, and Adults 18-34. The highest-rated Shark Week premiere night in three years, the programming event reached more than 5.3 million total viewers across Discovery Channel, discovery+ and Max on its first night.

Sunday night's telecasts averaged a 1.13 L3 rating among Adults 25-54 - a 9% increase from a year ago and the largest opening night growth in six years. Through the first four nights of Shark Week (Sunday-Wednesday L+SD), Discovery is the #1 network on cable in Adults, Men and Women 25-54, Adults, Men and Women 18-49 and Women 18-34.

"We were able to harness the strength of the Warner Bros. Discovery portfolio to cross promote Shark Week and now, with double-digit gains throughout the week, it is the highest-rated in three years - with every night outperforming a year ago," said Howard Lee, President of Discovery Networks and TLC. "It's a powerful example of how we can use our platforms to showcase high-profile programming events. Also, our collaboration with host Jason Momoa, the fan-favorite actor and conservationist who guides viewers through each night of programming, ensured that our first night was a success and set the stage for the week's strong performance."

"We engaged viewers across every brand and platform because we wanted to provide memorable Shark Week experiences for them, including offering an exclusive sneak peek of Meg 2: The Trench, the next big theatrical release from Warner Bros. Discovery," said Josh Kovolenko, Senior Vice President of Marketing, US Networks Group. "We also brokered various marketing partnerships with influential brands that are organically connected to our long-standing mission to highlight and celebrate sharks."
