It really doesn't come as a suprise that a Great Britain study shows that 20% of users watch a lot less traditional TV because they spend their time watching mobile and online video, and additional 23% say that they watch a bit less normal TV for the same reason.
This is because old-fashioned TV is boring, folks. And it keeps hammering commercials in your brain at least 10% of the time. On YouTube and similar services, I can watch what I want, when I want it. God help the traditional TV and media houses when online video quality improves.
