Upon reviewing the latest Nielsen 3 Screen Report, some mobile data looks interesting: 
- As of Q1 2008, 91 million (36% of all mobile phone subscribers in the U.S.) owned a video-capable phone. As
more subscribers upgrade to phones capable of receiving mobile video, subscription cost, promotion and network speeds will be the primary challenges to the growth of mobile video consumption.
- As of Q1 2008, there were already 13.9 million persons (6% of U.S. mobile subscribers) paying for a mobile video plan, up from 8.4 million (4% of all mobile subscribers)in Q1 2007.
- 4.4 million persons (2% of U.S. mobile subscribers or 31% of those who subscribe to mobile video) report that they watched mobile video with a mobile video subscription.
- In addition, 95 million persons (37% of U.S. mobile subscribers) subscribed to mobile Internet as part of their
mobile data plan in Q1 2008, a significant platform.
