Larry Page will lead Alphabet, while former Chrome and Android head Sundar Pichai will become the CEO of Google, now a subsidiary of the bigger company Alphabet. Sergey Brin will serve as Alphabet's president.
Google's shares rocketed up 6% in after-hours trading.

However, the true impact of the re-org probably won't be clear until Google/Alphabet next reports its earnings.
