For the third straight month, online video networks stood out in the Comscore Online Video Rankings. As in April and May, online video ad views reached an all-time high in June, eclipsing 20 billion for the first time. In addition, due to the relative lack of growth among non-ad videos, ads now account for more that 30% of all online video views.

After it became the most viewed ad network last month, Brightroll dropped back down to third after bringing in almost a quarter-billion fewer views in June. However, Google more than made up for this drop by scoring 700,000 more viewers than the previous month (and 3.26 billion in total). LiveRail rose to second with 2.39 billion views. The ad network that took the biggest hit was Tremor; thanks in part to its not-so-profitable IPO, it lost an eighth of its June view count.

Meanwhile, non-ad videos rose by more than 3.7 views between May and June, with Google/YouTube providing about half of the new views. Aside from Yahoo and Viacom switching places between 7th and 8th place, there were no changes in the top ten platforms. Meanwhile, top multi-channel networks VEVO, Fullscreen, Maker Studios, and Machinima saw a decrease in uniques, but all four had increased views and engagements.

While non-ad videos still greatly trump their corporate cousins in terms of engagement, the meteoric rise of ad videos is a disturbing trend for those creators who see the Internet as a place where one can escape commercial influence. I would suggest that all those people start Vining everything in their lives nonstop in order to restore the balance.
