LOS ANGELES, Jan 25 (Reuters) - Splashy Super Bowl ads for national advertisers like Coca-Cola Co and Budweiser always seem to set records, but sales of lucrative local commercials on stations owned by broadcaster CBS Corp will also hit an all-time high this year.
"It's huge compared with what CBS did three years ago," said Peter Dunn, president of CBS Television Stations. "Money is still coming in, so it's still not finished. We do think it's a record for total revenue."
Dunn said with eight days to go before kick-off, local ad sales are well above one analyst's estimate of $22 million for CBS's 16 owned and operated TV stations that will air the industry's biggest annual advertising spectacle on Feb. 3.
Ad sales are strong at all of the stations, particularly those for CBS' stations in San Francisco and Baltimore, the two competing teams' local markets. In New York, CBS' biggest owned-and-operated market, at least two local ads have been sold for about $1 million each, Dunn said.
He also said local ad rates were sharply higher, nearly double from where they were three years ago when CBS last aired the game.
Evercore analyst Alan Gould estimates the network will generate $225 million to $255 million in ad sales, and $30 million at its stations, up from $188 million for the network and $25 million at the stations the last time CBS had the Super Bowl in 2010.
Super Bowl ad time is expensive because the game delivers the year's biggest TV audience. More than 100 million people are expected to tune in when the National Football League's Baltimore Ravens battle the San Francisco 49ers.
While big multi-million dollar ad campaigns garner most of the attention, it is the local ads that actually yield higher profit margins, said RBC Capital Markets analyst David Bank, who pegged CBS stations' Super Bowl local ad sales at $22 million.
"It's massively profitable at the station level, much more so than at the network " he said.
Prices for the national commercial space have also jumped. CBS has said it is getting as much as a record $4 million for some of its 30-second national ad spots for the game.
Based on estimates by RBC Capital's Bank, CBS just nearly breaks even on the big national ad sales for the Super Bowl after accounting for NFL fees to air the game and other costs. By contrast, local ad sales generate about an 85 percent profit margin for the company, he said.
Dunn said there has been a flurry of interest for ad inventory at the stations level since last Sunday, when advertisers knew which teams would be playing.
The interest in Super Bowl Sunday has carried over to other shows placed before and after the big game, and the stations are getting higher rates as well, said CBS' Dunn. Many of the ads were placed in the last few days as sponsors rushed to the stations.
"The good news about having these two stations (in the teams' home towns) is that we have a lot of 'shoulder' programming that's local." said Dunn. "That's huge incremental revenue for having two stations in the Super Bowl."
For some sponsors, local ads are more desirable because they have a regional bent, while others buy local ads or clusters of local spots after failing to get a national spot.
Beer maker MillerCoors was forced to go local to get around the exclusivity for national Super Bowl ads purchased by rival Anheuser-Busch InBev for Budweiser and its other beers brands.
MillerCoors, a joint venture between Molson Coors and SABMiller, bought 15-second spots on local stations in the Great Lakes and Southeast regions to promote Redd's Apple Ale, a new apple-flavored malt beverage.
Characters from AMC's hit zombie series "The Walking Dead" also will appear on screen during the Super Bowl in 44 markets as Time Warner Cable pitches its TV and Web service.
The ads will promote its entertainment offerings on cable television, video on demand and mobile devices.
"It's much more efficient for us," Time Warner Cable Chief Marketing Officer Jeffrey Hirsch said. "We think there is a lot of value in having that kind of focused audience."
Other local Super Bowl buyers typically include regional restaurants, grocery chains or groups of auto dealers that band together so they can afford air time during the big game.
Companies can go hyper-local, too. Super Bowl viewers in Scranton, Pennsylvania, will see a promotion for Dunder Mifflin paper, a brand hatched on NBC's Scranton-located comedy "The Office." Quill, a unit of Staples Inc, sells paper to real-life customers under the Dunder Mifflin brand.
