The United States Justice Department’s probe into Apple’s business practices has expanded beyond digital music to include other types of media, according to a new report. Citing unnamed sources, the New York Post reports that the DOJ is now contacting large media and technology companies in addition to the major music labels and Internet music companies to learn their views on Apple. “The [Justice Dept.] is doing outreach,” an unnamed Hollywood industry source told the Post. “You can’t dictate terms to the industry. The Adobe thing is just inviting the wrath of everybody.” Another Post source at a media company said, “If Apple thinks it’s going to increase its monopoly with the iPad, it should look at the history of other walled gardens.” The New York Times reported last week that the Justice Department was looking into possible antitrust issues regarding Apple’s digital music business, in particular its efforts to keep music labels from giving Amazon early access to new release music.
