SAN FRANCISCO — Google co-founders Larry Page and Sergey Brin are stepping down from their roles at Alphabet, handing Google CEO Sundar Pichai the chief executive role at Alphabet, too.

Page was Alphabet’s CEO, while Brin was its president. 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 shareholder meeting even though he was still in the CEO role.
