Liberty Media, controlled by US cable TV pioneer John Malone, has posted a first-quarter profit of $254 million (€197.83m; £134.84m).

The figures, boosted by increased sales at the group's QVC shopping channel and the Discovery cable network, are in contrast to a year-earlier Q1 loss of $10m.

QVC sales for Q1 were up 14% to $1.46 billion, contributing to overall Liberty revenue of $2 billion, from $1.75bn in the same quarter last year.

Revenue from the company's Starz Entertainment Group climbed to $254m, but operating income fell to $36 million from $53 million.

Discovery Communications, of which Liberty owns 50%, posted revenue of $601 million, up from $527 million.

Looking ahead, the company says it has it raised its full-year outlook for QVC. It now expects revenue to rise by low double digit percentages, operating cash flow and operating income by mid-teens percentages.

Discovery's full-year revenue is expected to rise by mid-teens percentages, operating cash flow by low double-digits percentages and operating income by about 10%.

Colorado-headquartered Liberty also plans to complete a spin-off of its interest in Discovery and Ascent Media in the second quarter as part of Malone's plan to simplify the holding company's structure and appeal to more investors.
