Blackburn joined Amazon in 1998 after helping guide the company through its IPO at Deutsche Bank.

Blackburn returned to Amazon in May of last year to lead its media and entertainment businesses (Prime Video and Amazon Studios, Music, Podcasts/Wondery, Audible, Games and Twitch). With Blackburn's departure, there will be some shifts in Amazon's leadership.

Steve Boom, who has been leading our Music and Podcasting teams, will also now oversee Audible, Twitch, and Games businesses a" and report to Jassy. "This transition will happen effective January 1, though Blackburn will remain at Amazon through early 2023 to help ensure a smooth transition," said the Amazon CEO. Blackburn said that he is planning on retiring from Amazon in January, after more than 25 years and working closely with the company since its 1997 IPO. "I've decided to spend 2023 differently, giving more time to family, and feel strongly this is the right decision for me," he said. /IANS
