2011: the year that Internet radio went social | Radio Survivor

2011 was supposed to be the Pandora Takeoff Moment—the year that Pandora went public and solidified its absolute, total dominance over Internet radio and
music streaming. And coming out of the starting gate in February, it
sure looked like that was going to happen. Pandora’s S-1 form noted that
it had registered 80 million users as of January 2011, with a new one
signing up every second.
