MSNBC.com, together with Action Engine, has launched a multimedia ad-supported mobile news offering, reports ClickZ. MSNBC.com Mobile is reportedly one of the first free, ad-supported news applications for handhelds and offers news articles, videos and slideshows from various sources. The downloadable service will be promoted to visitors of MSNBC.com and the rest of the MSN network.

Action Engine provided the technology platform. MSNBC.com will sell ad inventory, which for now consists of 15-second pre-roll video and banner-like display ads. Windows Mobile is the exclusive sponsor for a three-month test period.

MSNBC.com Mobile is available only on Windows Mobile and Java devices, and users must have a data plan through their wireless carrier.
