As the summer heat beats down upon us it seems that it’s driven a lot of us indoors and into the cool embrace of online video. Over 180 million Americans tuned int to see 33 billion “videos” last month (June 2012) and a new record 11 billion video ads (see other article).

It’s good to see the online viewership still over the 180 million mark (180.373 vs 180.5 in May). The comScore determination of what is a video aside, it seems that less was viewed in June as it’s some 3.5 billion less with minutes dropping by 75 minutes per viewer in the month. So while viewers were about steady, the other stats dropped in June. However, the average length of videos viewed continued to climb adding 0.3 minutes to reach an all-time high of 6.8 minutes while video ad length remained steady at 0.4 minutes each. Video ads accounted for 25 percent of all videos viewed and 2 percent of all minutes spent viewing video online both are continuing trends as May saw 21.6% and 1.9% of all minutes, and May was 20.5 and 1.6.

In the top ten chart we see Google remains on top even adding 20 minutes per viewer and almost 3 million viewers. VEVO continued the drop it started previously as Facebook takes third. Viacom saw a jump over Microsoft. Amazon and Vimeo push Hulu and New Distribution off the list.

*A video is defined as any streamed segment of audiovisual content, including both progressive downloads and live streams. For long-form, segmented content, (e.g. television episodes with ad pods in the middle) each segment of the content is counted as a distinct video stream.

As far as the top ten YouTube Partners, VEVO remains on top. In fact, there are no real changes to the chart until you get to the bottom half where ClevverTV jumped Big Frame and IGN replaced MOVIECLIPS.
