At the Digital Hollywood conference today, MobiTV announced that it has 500k subscribers across all carriers offering its service. MobiTV offers mobile video/TV on several U.S. carriers, through two carriers in Canada and on Orange in the UK.

This may seem like a small number of total users, but it is a respectable start for a new content service that has only recently entered the market. Using the $9.99 per month price charged for the service on Sprint as a benchmark, carriers are already receiving $5 million per month ($60 million per year). Estimates have not been released yet for the revenue share paid to MobiTV or to networks for content.
