Google Sites Leads U.K. in Online Video Viewership

Google Sites ranked as the top U.K. online video property in April with 2.4 billion videos viewed, an increase of 58 percent versus year ago, driven by the popularity of YouTube.com, which accounted for 99 percent of all videos viewed on the property. BBC Sites ranked second with 79 million videos viewed, followed by ITV Sites (34.7 million videos), Megavideo.com (31.7 million videos), and Microsoft Sites (30.2 million videos).

“With nearly five billion videos viewed in the U.K. in April, online video is a powerful and growing vehicle for online advertising placement,” said Mike Read, SVP and managing director, Comscore Europe. “The online video market currently relies heavily on display ads for monetization, and in the coming months and years we can expect that video ads will play an even more prominent role. Despite the market’s overwhelming size and audience at this phase of the growth curve, it is also clear that we’re still in the early stages of advertising optimization and effectiveness in this increasingly important entertainment channel.”
