Google founders Larry Page and Sergey Brin have announced they are stepping down from top roles at the online giant’s parent company.
They will leave their respective roles as Alphabet’s chief executive officer and president but remain on the board.
Google’s CEO Sundar Pichai will become Alphabet’s CEO too, a statement said.
Alphabet was created in 2015 as part of a corporate restructuring of Google, which Mr Page and Mr Brin famously founded in a California garage in 1998.
The parent company was intended to make the tech giant’s activities “cleaner and more accountable” as it expanded from internet search into other areas such as self-driving cars.
The pair moved from Google to Alphabet when it was formed – saying they were making the jump to focus on starting new initiatives.
But in a blog post on Tuesday, the co-founders, both aged 46, announced they were stepping back from the day-to-day management of the company.
A joint letter said they would remain “actively involved as board members, shareholders and co-founders”, but said it was the “natural time to simplify our management structure”.
