Sharks keep hold on TV viewers' attention

LOS ANGELES (AP) — The popularity of "Sharknado" may have had a splash-over effect on Discovery Channel's Shark Week, which debuted with its highest-rated night ever in 27 years of telecasts, the network said.

More than 3.6 million prime-time viewers tuned in Sunday for a line-up that included "Air Jaws: Fins of Fury," according to Nielsen company figures Tuesday.

Shark Week enjoyed a social media bounce as well, with two of its Sunday shows making Nielsen's top 10 list of the most-tweeted about programs for the week of Aug. 4-10.

Live programming continued to prove a top summer TV draw, with three episodes of "America's Got Talent" ranking among the most-watched shows.
