On Tuesday night, shortly after First Lady Michelle Obama’s DNC speech, YouTube reportedly put a copyright blocking message on its live-stream video of the event. Making matters worse -- because YouTube is the official streaming partner of the DNC -- would-be watchers apparently encountered the same blocking message on BarackObama.com and DemConvention2012. Reached by Wired.com, a YouTube spokesman downplayed the blockage, explaining in an email: “After tonight’s live stream ended, YouTube briefly showed an incorrect error message … Neither the live stream nor any of the channel’s videos were affected.”
