The Obama Inauguration Live Stream Stats

President Barack Obama’s inauguration was a global moment, not just in terms of history and politics but also web participation. And now, the numbers are starting to roll in for Inauguration Day web video traffic. Was it the largest live stream audience ever, as we had suspected? It’s hard to say just yet, since the streams were spread out amongst so many outlets. But here are the numbers so far.

akamaiinaugurationAkamai Technologies (s AKAM), which powers many sites including CNN, said it had its largest single day on record of concurrent live viewership, with 7 million active simultaneous streams (the majority of them live) at about 12:15 p.m. ET today.
