With the game less than four months away, advertising options include the Detroit People Mover, highway billboards and teams of representatives who hand out product samples.

More than 125,000 visitors are expected to visit the Detroit area for the Feb. 5 game and national and local marketers have been jockeying for top advertising space.

Detroit Transit Corp. officials said advertisers seek to purchase space on the outside of the People Mover's monorail cars. The spaces typically cost $30,000.

But for January and February, the DTC is auctioning off the spaces, as well as space in its 13 stations. It marks the first time advertising has been offered at the station sites.

"The potential exposure for advertisers is mind-boggling," Dennis R. Green, the DTC's marketing director, told the Detroit Free Press for a Tuesday story. He said ads on the monorail cars will give companies "unprecedented worldwide exposure."

Bids are already in but DTC officials haven't revealed how much money they expect the auction to make. They could award the space as early as this week.

Viacom Outdoor representatives won't say if the company has raised billboard rates for the weeks surrounding the Super Bowl.

The company has sold 75 percent of the space on its 2,000 Detroit area signs.

"Our bookings are way ahead of where they would normally be in the first quarter (of the year)," said Tom Carroll, vice president of Viacom Outdoor's central region. "It's been a pleasant surprise, but we still have billboards available."

The company typically charges $7,500 to $10,000 for billboards along major interstate highways.

Gateway Outdoor Advertising has booked about 500 of its 1,500 small-sized Detroit area billboards for Super Bowl time. The Hackettstown, N.J., company charges $250 to $1,000 a month and rates will stay the same in January and February.

"We've had a lot of inquiries," said Durand Walker, Gateway's vice president and regional manager. "So far, though, everyone's just exploring their options."

Mobile Marketing Group in Detroit operates ten billboard vehicles -- trucks that carry advertisements on four sides -- costing $650 to $1,500 for eight hours. The group has received inquiries from local and national marketers, said Rodney Price, Mobile Marketing's president and CEO.

No spots have been sold for Super Bowl week but the group likely will sell 12-hour spots for $2,000 to $2,500.

The company also hasn't sold any street teams -- groups of people who hand out company materials during events.
