Google, the search giant and would-be multi-media advertising enabler, has opened up the bidding on its much-talked-about print venture. AdWords advertisers can now bid for 1 page, 1/2 page and 1/4 page ads in nearly 30 different lifestyle and technology magazines.

The test's purpose, the company says on its site, is to assess AdWords advertisers' demand for space in print publications. Google began a limited test of the service with select advertisers in August.

Titles involved include Hachette Filipacchi books like "Car and Driver" and "Ellegirl;" Future Publishing titles like "Pregnancy" and "Women's Health and Fitness;" and Martha Stewart Omnimedia's "Martha Stewart Kids" and "Martha Stewart Living."
