Revenue climbed 12% to $1.03 billion from $44 million in the fourth quarter of 2012.

Liberty Media, which acquired a controlling interest in SiriusXM in January, said operating income was $189 million in the fourth quarter versus an operating loss of $60 million a year earlier. Net income for Liberty sank to $65.2 million from $156.2 million in the same period a year ago.
