With millions tuning in from their PCs to watch President Obama’s Inauguration speech, it was one of the biggest tests yet for live video streaming. But live streaming failed. CNN.com kept bumping viewers into virtual waiting rooms. This happened to me in the middle of Obama’s speech. I had to keep hitting refresh, but missed half the speech. The stream on Hulu was even worse, with the video frozen and the audio coming in and out. And forget about Ustream. I couldn’t even get any audio. This seemed to be the general experience out there, based on other reports.
