Time Warner profits boosted by advert sales
A jump in television advertising sales helped Time Warner to a better-than-expected 21% jump in profits in the last three months of 2010.
The US media firm made $769m (£474.3m) in the period.
At its cable networks division - which includes CNN and TBS - sales rose 14% to $3.3bn on strong subscription fees and advertising sales.
Analysts said that other media companies were also likely to report increased advertising revenues.
These are expected to include News Corporation, which announces results later.
"It's a sign of just how strong the cable advertising network market is," said Alan Gould, an analyst with Evercore Partners.
At its filmed entertainment division, which includes Warner Bros, revenue rose 10% to $3.6bn in the fourth quarter.
But at Time Warner's publishing business, which produces Time, People and Sports Illustrated magazines, turnover fell 4% to $1.1bn on lower advertising and subscription sales.
