Judge orders Steve Jobs to testify in iTunes antitrust case

A federal magistrate judge has ordered Apple chief executive Steve Jobs to answer questions in an antitrust lawsuit accusing the firm of anti-competitive behavior in the market for online music, according to a report from Bloomberg.

The 2005 lawsuit from customer Thomas Slattery argues the Cupertino, Calif.,-based firm limited consumer choice by linking its iPod music players to its iTunes music store. 

The judge said lawyers for the plaintiffs may question Jobs for up to two hours solely on the subject of software changes made in October 2004 that rendered digital music files from RealNetworks incompatible with iPods.

Slattery claims Apple's FairPlay software prevents iTunes digital music files from being played on other manufacturers' devices. FairPlay also prevented music downloaded via other online stores from being played on iPods.

Jobs is currently on medical leave from his position, though he has made a few public appearances such as dining with President Obama in Silicon Valley last month and taking the stage earlier this month to unveil the iPad 2.
