SAN FRANCISCO (AFP) - A US jury on Tuesday found in Apple's favour in a US$350 million (S$455 million) lawsuit that accused the tech giant of illegally forcing iPod users to purchase their music on its iTunes service.

After a trial which dramatically featured testimony from late Apple founder Steve Jobs - presented in a video recorded before he died three years ago - the jury ruled for Apple in the federal antitrust case.

The class-action suit said iPod buyers between 2006 and 2009 were blocked from buying music from other vendors, advancing Apple's dominant position on music downloads.

"We thank the jury for their service and we applaud their verdict," Apple said in a statement.

"We created iPod and iTunes to give our customers the world's best way to listen to music. Every time we've updated those products - and every Apple product over the years - we've done it to make the user experience even better."
