With a little help from Andy Samberg, Discovery’s Shark Week got off to one of the annual programming event’s best Sunday night numbers ever.

Shark Week opened to 3.3 million viewers its first hour for Great White Invasion and 3.0 million for Jaws Comes Home at 10 p.m. The opening block was down slightly in viewership from last year. Among adults 18-49, Jaws was the No. 2 program on cable last night behind HBO’s True Blood.

Discovery is particularly proud of its strong female demos last night since Shark Week hasn’t historically been much a draw among women.

What’s really impressive about this is that this week marks the 24th year Discovery has aired Shark Week and it’s still going strong. The network also made a smart choice by tapping Samberg as host to put a familiar face on the week.
