Decline in TV viewership has the networks worried

NEW YORK — Maybe they're outside in the garden. They could be playing softball. Or perhaps they're just plain bored.

In TV's worst spring in recent memory, a startling number of Americans drifted away from television the past two months: More than 2.5 million fewer people were watching ABC, CBS, NBC and Fox than at the same time last year, statistics show.

Everyone has a theory to explain the plummeting ratings: early daylight-saving time, more reruns, bad shows, more shows being recorded or downloaded or streamed.

Scariest of all for the networks, however, is the idea that many people are now making their own television schedules. The industry isn't fully equipped to keep track of them, and as a result the networks are scrambling to hold on to the nearly $8.8 billion they collected during last spring's ad-buying season.

"This may be the spring where we see a radical shift in the way the culture thinks of watching TV," said Sarah Bunting, co-founder of the Web site Television Without Pity.

The viewer plunge couldn't have come at a worse time for the networks — next week they will showcase their fall schedules to advertisers in the annual "up front" presentations.

The networks argue that viewership is changing, not necessarily declining. Some advertisers respond that they are no longer willing to pay full price up front to reach viewers that may not tune in later.

This fall, both sides will be watching what happens with families like Tony Cort's. During prime-time, Cort, his wife and four kids tend to scatter to computers or other activities in different parts of their New Jersey home. (Not during "American Idol" or "Lost," though.) They're definitely watching less TV, said Cort, who runs a Web site for martial arts aficionados.

"I remember when '24' was on, that was something there was a lot of interest and excitement about," he said.

News flash: "24" is still on. Its ratings are down, too, amid a critically savaged season.

More bad news abounds. NBC set a record last month for its least-watched week during the past 20 years, and maybe ever — then broke it a week later. This is the least popular season ever for CBS' "Survivor." ABC's "Lost" has lost nearly half its live audience — more than 10 million people — from the days it was a sensation. "The Sopranos" is ending on HBO, and the response is a collective yawn.
