According to this report in the New York Times,
CNN.com and ESPN.com are featuring video much more prominently on their home pages, often prompting visitors to press play before they begin to read. Even The Wall Street Journal has moved its video player front and center with a twice-a-day live newscast on WSJ.com.
The reason quite simply is that video is benefiting from the higher cost-per-thousands, or C.P.M.’s, that ads on those videos command.
The attention to video mirrors changes in how consumers are experiencing news. Major events — be it the presidential election or the death of Michael Jackson — bring a surge in video stream viewings by new users, and each time some of them stick around.
