Driven by ubiquitous broadband, increasingly smart devices and free, easy-to-use video chat services, the number of video calls that consumers make is expected to increase nearly ten-fold over the next five years. That will lead to an explosion in mobile video chat revenues, which are expected to reach $3.4 billion by 2015, according to a new report by GigaOM Pro. (subscription required) The report, entitled “Can You See Me Now?: The New World of Consumer Visual Communications,” forecasts that consumers will make 29.6 billion video calls in 2015, up from just 3.2 billion this year. During that time, most video calls will be made over PCs, but by 2015, the number of video calls made over the computer will level out as consumers take advantage of video chat services available on mobile devices and Internet-connected TVs.
