The co-founders of Google are stepping down as executives of its parent company, Alphabet, ending a remarkable two decades during which Larry Page and Sergey Brin shaped a startup born in a Silicon Valley garage into one of the world's largest, most powerful -- and, increasingly, most feared -- firms in the world.
Sundar Pichai, who has been leading Google as CEO for more than four years, will stay in his role and also become CEO of Alphabet.
Page was Alphabet's CEO, while Brin was its president. The president's role at Alphabet is not being filled. Both founders promised they plan to stay actively involved as board members and shareholders, and lauded Pichai for his leadership of the company.
Page and Brin both have been noticeably absent from Google events in the past year. Both stopped making appearances at the weekly question-and-answer sessions with employees, and Page didn't attend this summer's Alphabet shareholders meeting even though he was still in the CEO role.
Alphabet -- an umbrella corporation that the two created in 2015 -- still boasts Google as its central fixture and key moneymaker. But it's also made up of what are known as "other bets," or longshot projects. That includes drone company Wing and self-driving car firm Waymo.
Alphabet has been positioning Pichai as the de facto leader for quite some time -- making him the top executive voice at shareholders meetings, on earnings call and as a spokesman at congressional hearings.
Page and Brin announced the news in a blog post Tuesday, saying the company has "evolved and matured" in the two decades since its founding.
"Today, in 2019, if the company was a person, it would be a young adult of 21 and it would be time to leave the roost," they said.
The pair still hold more than 50% voting shares of Alphabet. According to an Alphabet SEC filing in April, Page holds 42.9% of the company's Class B shares and 26.1% of its voting power. Brin holds 41.3% of the Class B shares and 25.2% of the voting power.
Google has nearly doubled its headcount since Pichai took over as chief executive, growing from a company of 59,000 employees to 114,000 now.
Google's stock increased less than 1% in after-hours trading after the news was announced.
Brin and Page met as Stanford University graduate students in 1995 and started the company soon after. What started as a way to catalog the growing internet has now become one of the most powerful companies in the world. Google dominates online search and digital advertising. It's hard to make it through a whole day without using one of Google's services -- ranging from online tools to email, cloud computing systems, phones and smart speaker hardware.
Page dropped out of graduate school at Stanford to start Google and doesn't have a business degree. He grew up in Michigan, where his late father, Carl, was a computer scientist and pioneer in artificial intelligence, and his mother taught computer programming. Page began working on personal computers when he was just 6 years old in 1979, when home computers were a rarity. The geeky impulses carried into his adulthood, leading him to once build an inkjet printer out of Legos.
