RPT-U.S. writers strike could mean big changes in advertising

NEW YORK, Nov 12 (Reuters) - The Hollywood screenwriters strike is less than a week old, but already concerns are spreading that a long walk-out could drastically change the face of television advertising.

The $70 billion television advertising industry is still considered the best way to promote brands and products, despite the buzz over advertising in digital media like cell phones and video games.

A prolonged strike by screenwriters, however, could lead to big changes. Audience ratings are likely to slip without new TV shows to watch, and as viewers move elsewhere, so too will advertisers.

"I don't know how long it will take, but viewers will start to go to other places, and we as advertisers have to follow them," said Lisa Herdman, vice president of network programming at RPA, an advertising and media buying agency. "Whether we will go back to TV is another question altogether."

In many ways, experts say, the strike could not have come at a worse time for the television industry, given how much competition it faces for audiences and advertisers from the Web, iPods and every other sort of digital media.

"Marketers have more alternatives than ever before on how and where to spend their money," said Brad Adgate, director of research at Horizon Media, an independent media services company. "There's more than the 30-second TV spot. There are opportunities out there and dollars are going to follow the eyeballs."

He added: "While television still remains the entertaining center of your living room, there is some concern that the longer this strike stretches out people's habits will change."
