Pandora Media Inc. said its personalized online radio service doubled in size this year, topping 40 million registered users. Of those, some 15 million people visited the Web site each month, said Tim Westergren, Pandora’s chief executive. Almost all stream the radio content.

CC Media Holdings Inc.’s Clear Channel Radio (CCO) says it has about 8 million listeners who stream its programming each month.
