Google founders Larry Page and Sergey Brin have announced they are stepping down from top roles at the online giant's parent company, Alphabet.
Larry Page and Sergey Brin wrote that Google's CEO Sundar Pichai will become Alphabet's CEO too, a statement said.
They will leave their respective roles as Alphabet's chief executive officer and president but remain on the board.
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 pair moved from Google to Alphabet when it was formed - saying they were making the jump to focus on starting new initiatives.
In a blog post, 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".
"We've never been ones to hold on to management roles when we think there's a better way to run the company. And Alphabet and Google no longer need two CEOs and a President," their letter said.
They also declared it was time to "assume the role of proud parents - offering advice and love, but not daily nagging" and insisted there was "no better person" to lead the company into the future than Mr Pichai.
