MSN Mobile Web is a Web portal for cellphone browsers, designed to give mobile users "handy on-the-go" access to the Web, including directions, email and entertainment.

The company offers advertising, including banner and text placements, on the MSN Mobile home page and its five channels--sports, news, entertainment, weather and money. The mobile ads will not include video formats, and will be sold on a CPM (or cost-per-impression) basis.
