Media consumption is all about the three screens. One that’s big, one that’s small and one that’s just right.

According to The Nielsen Company, time spent viewing online video content increased 13 percent in December. However, that increase of Internet video viewing did not affect traditional television viewing.

‘Rather than Americans replacing TV with the Internet or a mobile device, they are just consuming more ‘- often simultaneously,’ said a Dec. 15 report by The Nielsen Company. ‘Despite the availability of video content on the Internet, TV viewing is up about 20 percent over the last decade, and the average American watches 141 hours of programming each month.’

Lance Porter, mass communication professor, said because television viewing is a sit-back-and-relax activity, it allows consumers to surf the web, talk or text on cellphones and multitask at other activities at the same time, which contributes to the trend of three screens.
