Apple is accused of maintaining an illegal monopoly on the digital music market in an antitrust lawsuit filed on 31 December.

The plaintiffs claim Apple dominates the market for online video, music and digital music players, and that this dominance is a violation of the Sherman Antitrust Act.

The filing maintains that Apple controls 75 per cent of the online video market, 83 per cent of the online music market, and 70 per cent of the market for digital music players, reports Information Week.

It is also claimed that Apple CEO Steve Jobs called the iTunes Store “the Microsoft of music stores” in a meeting with financial analysts, suggesting that he recognises Apple’s monopolistic presence in the market.
