Mobile video streams are on the rise. Pay-TV subscribers are cutting their cords in droves.  Right?  Not so fast, says Nielsen.

According to a new report from the respected agency, TV still leads the market in video viewership (not to mention ad spend) by a large margin.  Based on third-quarter 2013 data, viewers spent, on average, 55.5 hours watching traditional TV versus nearly 15 hours on time-shifted TV; 34 hours using mobile-web or an app on a smartphone; and about 28 hours via internet on a computer in the quarter last year.
