United Mobile Broadcasting Corp. (UMBC) is a new medium for digital broadcasting and advertising.

Mobile broadcasting is an extension of the wireless revolution and is being developed to provide audio, video and multimedia contents to mobile communication devices (cell phones, PDAs, consoles, etc.) and in ¡°moving environments¡± (trains, planes, buses, etc.).

UMBC combines the concept of mobile broadcasting with
a commercially viable, non-subscription business model that generates revenue through the sale of advertising. UMBC is one of the first mobile broadcast providers on commuter trains and subways in North America.
