The average price of a gallon of regular gasoline rose 7 cents to $3.26 in the past two weeks, according to industry analyst Trilby Lundberg’s survey of 7,000 filling stations nationwide.

The highest average price for self-serve regular was $3.66 a gallon in San Francisco, the survey found.

The lowest was in Newark, N.J., at $3.03 a gallon.

The average price for the Seattle-Bellevue-Everett area was $3.52 Sunday, according to the AAA Daily Fuel Gauge Report.

Rising prices have caused demand for gas to fall 1.8 percent from a year ago, the Energy Department last week.

Forbes to sell ads for blogs

Traditional media companies trying to stem the flow of ad dollars to big Internet companies are increasingly building ad networks of their own, anchored by their brands.

The latest, Forbes, is announcing today it will start selling ads for about 400 financial blogs.

In recent months, Conde Nast, Viacom, CBS and other major media companies also have unveiled topic-specific ad networks to lure advertisers that want to buy more ads than any single site can sell.

These media networks may have a tough time competing with the larger networks of thousands assembled by Google, Yahoo, Microsoft and AOL.

Those companies have been spending at least $11 billion collectively to buy smaller ad networks and technologies.

Videoconferences

Meetings brought into living rooms

Quanta Computer, a leading contract maker of laptop computers, and OoVoo, a maker of video chat software, today are unveiling a gadget that plugs into HDTV and brings high-definition videoconferences to the home.

Users of the Quanta Video Messenger will be able to hold chats from their living rooms with others with the device as well as anyone who is running OoVoo’s software on a PC.

The gadget, which connects to the Internet, is expected to be available later this year, OoVoo Chief Executive Philippe Schwarz said.

He said OoVoo is in early discussions with phone and cable companies about building the videoconferencing function into their set-top boxes.

The Quanta Video Messenger will support a resolution of 1280 by 720 pixels at 30 frames per second.

Best Buy

$50 rebate offered for HD-DVD buys

Now that Blu-ray has won the high-definition format war, Best Buy is hoping that there will be no hard feelings.

The big-box electronics retailer said it will hand out more than $10 million in gift cards to customers who put their money on the vanquished HD-DVD technology.

Eligible customers will get $50 gift cards for every HD-DVD player or attachment purchased at a U.S. Best Buy before Feb. 23, the day HD-DVD-maker Toshiba ceded the contest to Blu-ray.

Gift cards will be mailed automatically to Reward Zone members, customers who ordered online and those who purchased a service plan.

The cards should arrive by May 1, Best Buy said.

Everyone else must call 888-237-8289 with a proof of purchase. Stores can’t issue the gift cards.

There’s no need to junk your HD-DVD player, of course. But if you don’t want old technology cluttering up your den, Best Buy has expanded its trade-in site at www.bestbuytradein.com to include HD-DVD players.
