Television listings publisher Gemstar-TV Guide International posted a loss of $953.8 million (€975.4m; £613m) for its second quarter, widening from $134.8m a year earlier.

The company – in which Rupert Murdoch’s News Corporation is the principal shareholder – was hit by a $1.3 billion write-down on the value of its TV Guide magazine, once America’s top-selling weekly title.

Also, revenues fell 15% to $271.7m, despite rising turnover at its e-commerce arm. Revenues were down at both its magazine unit and its licensing arm, which holds patents to on-screen listings technology.
