T-Mobile has teamed up with AOL for a high-profile promotional effort for the new G1 phone. Through its Platform-A ad division, AOL is delivering one billion impressions on Nov. 10 and 11 that will reach an estimated 81.5 million consumers during the 48-hour period.

As the most expansive two-day ad buy to date for Platform-A, the "T-Mobile Billion Block" will dominate a significant portion of its inventory across AOL's own sites and those in its Advertising.com ad network.

AOL can use the sales boost. The Web portal's online ad revenue slipped 6% in the third quarter, suggesting that the integration of a series of acquisitions into Platform-A has not paid off yet. An AOL spokesman said the company wants to do more high-impact campaigns like the "Billion Block" push that leverage reach and frequency.--Mark Walsh
