Major Multitasking

If you try to add up all the hours people report spend online, consuming media, sending messages and so forth, you realize that if those people have jobs or go to school, they must be multi-tasking. More important for anybody whose business touches advertising, online advertising spending lags time spent by users on their media. Over time, that gets rectified as advertisers move more money in an online direction.

Hence Google's interest in the mobile Web.
