Although Google’s purchase of YouTube hasn’t paid of financially, it has clearly made Google a giant in the world of online video, displaying more than 13 billion videos during the month of April. On Tuesday, comScore, which monitors online usages of e-commerce, advertising and video, released its April data of video usage on the Internet. According to a company press release, 178 million United States Internet users, or 83.5 percent of the total American Internet audience, watched some form of video online during April. YouTube dwarfed other competitors, dominating the attention of 135 million Web surfers, who watched more than 13 billion videos on the service. Hulu, which offers videos from mainstream media outlets, including ABC, Fox and NBC, was a distant second streaming 958 million views during the same period. Other online video outlets included Microsoft, which offers video through it’s Zune network, showed 644 million online videos, and Viacom, which owns the MTV network, showed 384 million video views. ComScore also said that all the video viewed online during the month added up to 30.3 billion clips. The average length of these videos was a relatively short 4.4 minutes long, which comes to an astounding 253,652 years of video.
