According to three years of In-Stat surveys, consumer interest in mobile video is increasing, albeit not as quickly as interest in mobile music. In 2006, 14.2% of respondents could be considered likely adopters of mobile video. In-Stat forecasts that revenue from mobile video for entertainment purposes could grow to over $6 bln per year by 2011. 44% of respondents who own music-playing handsets have not added any music files to their phones.
