As some Associated Press member newspapers criticise the fee structure being implemented next year, a sizable number are still interested in taking advantage of its growing web tools.

According to the Associated Press, 500 newspapers have signed up for AP Member Marketplace, the online system allowing its subscribers to exchange stories, photos and graphics, according to paidContent.

The service, originally unveiled in April, is expected to have some enhancements this week. According to paidContent, 53 papers in Ohio, 45 in Pennsylvania and 26 in Texas have requested for access so far. Moreover, there are already 20 states where at least 10 member newspapers have signed up.

The offer of additional online capabilities is being provided due to tough challenges the AP faces from the Web. Sites like Poltico.com, positioning itself as something of a wire service, targets struggling newspapers as part of its new ad network. The AP, however, with 1,500 members, hopes to maintain its advantage against Poltico and other rivals by serving as a broker for members to share news, paidContent reported.
