Video-based entertainment includes video games, Internet video, DVDs and mobile video, TV Week reported.

However, not all sectors in the video pie will grow. According to the study, PC, online video and mobile video consumption will boost to about 2.9 hours per day in 2013, from merely less than one hour today, while TV will shrink in market share.

TV viewing will remain constant at about four hours per day, while its share will stay steady because consumers will watch more TV content on-demand or on digital video recorders, and younger users will shift away from TV.

Actually, many of the young generation have already done so. Today, among the 12-to-24 age group, about 42 percent of its video-based entertainment is viewed on TV, compared to 64 percent of the population average, according to TV Week.

“People are spending a lot more time with alternative forms, like PC-delivered video. We believe the pie is expanding, and the appetite for video is remarkable, and non-video consumption on the net is converting, and there is and will be ambient video everywhere,” said Kaan Yigit, analyst with Solutions Research Group.
