As thousands of Sundance Film Festival-goers lined up Saturday to see independent films on the big screen, a couple hundred piled into a room to talk about the little screen. New mobile technologies like the video iPod and cell phones with video capability have already created demand for bite-size content. But many wonder whether such devices will become conventional outlets for film distribution, and whether consumers will watch such content on a small screen. The answer to both questions is yes, at least according to a panel of executives in the emerging mobile content industry. And they seemed to agree that the viewing of mobile content won’t take the place of regular TV watching or movie-going. Rather, it’s something consumers will use while riding a train or waiting in line at the DMV.
