Industry-leading webcaster Pandora this week announced its listening hours, share of total U.S. radio listening, and number of "active listeners" all grew in December.
Pandora reports streaming 1.39 billion hours of content last month. That's up from both November (1.27 billion) and December 2011 (906 million).
This means, says Pandora, that its share of all U.S. radio listening is now 7.19%. The webcaster reported its U.S. radio share as 7.09% in November, and 4.71% for the previous December.
Finally, Pandora's pool of "active listeners" grew to 67.1 million by the end of last month, up from 62.4 million in November and 47.6 million a year earlier.
