BUSINESS BRIEFING

Blockbuster Inc. plans to offer movies that can be watched on Motorola cellphones. It marks the struggling rental company’s first step into mobile video and is its latest effort at chasing down the customers that have abandoned its traditional video stores.

Blockbuster offered few details on the plan, which expands on the Dallas company’s OnDemand movie downloading service offered through set-top boxes for TVs. It did not say when the phone service would be available or how much it would cost.
