Videos on the iPad and other tablets look great, and increasingly apps are being created specifically for watching videos on tablets. There is just one problem: they cannot be found by search. This problem is true for information in all apps in general, but it is particularly one for video. A couple weeks ago, I moderated a panel at Beet.TV's Video Strategy Summit where this topic came up. In the video clip above, Ross Rubin, director of industry analysis at the NPD Group, points out that there is no electronic program guide for video apps, which "makes it very difficult to discover video." If you have a thousand video apps, that makes it very hard to find any one video.
