In a new report by IHS Technology detailing the consumption of video/streams relating to eSports, the latest report shows that around 2.4 billion hours of videos were viewed in 2013, making an increase that nearly doubled the 1.3 billion recorded for 2012. In terms of ranking for popularity, IHS reported that League of Legends was the most viewed eSport in 2013 by number of hours watched, followed closely by Dota 2 and StarCraft II.

In addition to the numbers from last year and the large growth, IHS also reports that it projects the trend to continue greatly through 2018, especially noting the rise in popularity due to services like Twitch, Azubu, and MLG that focus specifically on eSports, while other outlets like YouTube and Dailymotion provide other ways to view eSports in a more general sense.
