Interactive TV ads are clicking with viewers

— -- Looking for ticket buyers, the Los Angeles Sparks women's pro basketball team recently tried a new ad play: A TV commercial during which viewers could press a button on their remote to get a team brochure.

Hundreds responded. "Whoever was on our billing information as head of household got the information," says Jim Heneghan, ad sales chief for cable company Charter Communications, which created the "interactive" TV ad and sold the time to the Sparks.

Cable operators such as Charter, as well as their satellite TV rivals, all are experimenting with such ads. Their goal: battle Internet media for ad dollars by merging a TV commercial's impact with former Web-only selling points such as interactive content, ad targeting based on consumers' personal data and precise effectiveness measurement based on how many people click on an ad for more information.

With a traditional 30-second spot you only know how many people saw it, says Sam Chadha, marketing director for deodorants at consumer products giant Unilever, which has used interactive ads for several products, including Degree deodorant. "Interactive TV lets marketers also study consumer behavior in response to the ad."

Making TV spots work harder is one of the ad industry's most discussed — and elusive — goals. Already, two-thirds of big marketers said standard TV ads became less effective in the past two years, according to a January survey by the Association of National Advertisers and Forrester Research.

The good news for sellers of TV ad time: 43% also said they are eager to try interactive TV ads.

•TV ads or video-on-demand-offerings that let viewers order brochures, coupons or samples by pressing a button during the ad or video clip. A California mattress retailer offered a coupon for a free pillow and got about 1,000 requests in the first two weeks of the ad's airing.

•Interactive brand messages that are part of the TV programming. Unilever's Bertolli food brand, for example, sponsored polls and viewer voting during Bravo reality show Top Chef 3 Miami.
