The Federal Trade Commission will be the agency to review Amazon.com Inc’s proposed acquisition of Hollywood studio MGM, according to people familiar with the matter, just as the commission gets a new chairwoman who has been disapproving of the online behemoth’s expansion.Amazon last month revealed its deal for MGM, which would boost its Prime Video streaming platform in a market that includes rivals such as Netflix Inc. and Walt Disney Co. MGM has a library of over 4,000 firms, including the James Bond franchise, and a television catalog that includes “The Handmaid’s Tale” and “Vikings.”Companies doing substantial mergers have to submit their deals for government antitrust review. The FTC shares antitrust authority with the Justice Department, and the two agencies detach the work of reviewing proposed deals. The department has recently reviewed transactions involving video content, including Disney’s acquisition of 21st Century Fox and AT&T Inc’s acquisition of Time Warner, a deal the department unsuccessfully attempted to block in court.During recent interagency negotiations, the FTC acquired the right to review the Amazon-MGM deal. The FTC pushed for jurisdiction over the merger review because it already has an open, wide-ranging antitrust investigation into Amazon’s business practices.
