The YouTube blog just announced that U2 and YouTube will partner to offer a live webcast of the band’s concert at the Rose Bowl in LA this Sunday, October 25 at 8:30 p.m. (PT). YouTube recently launched its foray into the concert webcast space when it offered up a live stream from the Outside Lands Festival, but this is definitely a bigger step in terms of the size of the artist and the potential audience and online traffic.
