Bill Gates has stepped down from the board of Microsoft to spend more time on his philanthropic endeavors, the company announced Friday afternoon. Though he will remain technology advisor to CEO Satya Nadella, this move reduces his involvement with the company to the lowest level it has ever been.

Gates led Microsoft from the ’80s all the way through 2008, when he left to dedicate himself more fully to the Bill & Melinda Gates Foundation, through which he has channeled a great deal of his immense wealth towards global health concerns.
