Feb 27 (Reuters) - Liberty Media Corp, the media holding company controlled by John Malone, said its quarterly revenue fell by more than half in the fourth quarter.
It said in a statement the decrease in revenue was related to a one-time recognition of deferred revenue at one of its businesses, called TruePosition, a year ago.
Its revenue fell 52 percent to $467 million, compared to $973 million a year ago.
The company said its operating income was $25 million, compared to $293 million a year ago.
Liberty owns stakes in a variety of businesses, including Sirius XM, Barnes and Noble Inc, Concert promoter Live Nation Entertainment Inc and the major league baseball team, the Atlanta Braves.
