Justice Department's antitrust investigation in early stages

Apple‘s digital marketing tactics are reportedly set to be the subject of an inquiry by the Justice Department in the US.

The New York Times reports that the inquiry is based around allegations that the company has been persuading record labels not to give exclusivity deals to Amazon.com, a rival of its own iTunes service.

The sources who revealed the information to the newspaper spoke on the condition of anonymity, with representatives for Apple, Amazon.com and the Justice Department refusing to comment.

The Amazon.com-related allegation first surfaced in March, when reported by Billboard.com.

It was claimed that Apple pulled marketing for songs their rival had as part of an exclusivity deal.

Apple currently has 69 percent of the online music sales market in America. Amazon.com is the second-largest online music retailer in the country, with eight percent.
