SHARK WEEK RETURNS ON AUGUST 2 WITH THRILLING, ACTION-PACKED PROGRAMMING

-- Six Premieres to Air in 22nd Annual SHARK WEEK, Including Drama Based on True Story That Inspired �Jaws' --

(Silver Spring, Md.) � People have long been fascinated with the ocean's apex predator. But before 1916, average Americans knew very little about sharks. It was that year sharks made headlines as the New Jersey shore became a feeding ground, when five people were attacked in 12 days, triggering a nationwide panic. It was the first multiple shark attack in American history, and the reason we fear sharks to this day. BLOOD IN THE WATER is a gripping two-hour drama that brings to life the true story that inspired Jaws, and kicks off this year's SHARK WEEK on Sunday, August 2, 2009, at 9PM ET/PT.

SHARK WEEK, cable's longest-running event, will feature six premieres this year. Find out if sharks behave any differently during the day than at night; what makes certain areas of the world shark attack �hot spots�; and what still puzzles scientists about the most feared shark of them all � the great white. The week will be rounded out by some of the most popular and memorable programs from past years.

Once again this year, Discovery Channel will educate the public about the plight of sharks around the world through public service announcements produced in conjunction with SHARK WEEK marine conservation partner Ocean Conservancy. The PSAs will air each night during primetime, informing viewers about threats currently facing plummeting shark populations.

In its 22nd year, SHARK WEEK remains a huge ratings hit. Last year (2008), SHARK WEEK was watched by 29.1 million viewers, compared with 27.2 million in 2007. Two 2008 premieres earned a place on the list of the top 10 rated SHARK WEEK programs of all time (reported since 1996, based on P2+ Delivery): the MYTHBUSTERS: SHARK SPECIAL and DIRTY JOBS: GREENLAND SHARK QUEST.
