New data from Juniper Research found that over 136 billion adult videos will be watched in 2015 alone, with the figure set to grow to 193 billion by 2020. On a global scale, each smartphone user of adult content is expected to watch an average of 348 videos this year. Overall, video views are forecast to grow by almost 55 per cent by 2020. While there will be a marked increase in usage levels in developing markets, net growth will be greatest in the U.S., with other mature markets such as Western Europe seeing a more modest increase. In developing regions, service uptake will be rapid, driven by increasing availability of 4G and Wi-Fi, as well as increases in smartphone and tablet ownership. Report
