The FIFA World Cup was watched by millions of people around the world and according to MobiTV's data those with larger displays on their smartphones watched for longer periods than those with smaller screens. MobiTV reports they delivered more than 100 million minutes of coverage from ESPN Mobile TV with 100 percent uptime. Here is what their data showed:
I am not sure what device(s) was considered for the 5 inch screen data and requested this information to give me a clearer picture here, but as you can see there is quite a difference between the 4 inch and 3 inch sizes. The 4 inch devices are those like the HTC EVO 4G, Droid X, and HTC HD2 while most every other smartphone today falls in the 3 inch range (3.1 to 3.7 inches).
A coworker has an iPhone 4 and I do think the display is incredible, but I honestly find my 4.3 inch EVO 4G display to be better for watching movies and video content. The kickstand on the EVO 4G is also a major bonus for watching extended periods of video content.
The MobiTV data also showed that Android users led the pack with an average of 125.7 minutes per viewer. BREW and Palm were second with 84 minutes, the iPhone third with 77.8 minutes, RIM BlackBerry devices fourth with 65.4 minutes and Windows Mobile with 62.7 minutes.
