Here are all the companies and divisions within Alphabet, Google’s parent company

It’s been exactly a year since Google blew up its entire corporate structure to form a new parent company: Alphabet.

The shake-up happened with the idea that it would allow all of its businesses to operate more effectively and efficiently, a move the company was said to be considering for four years. The move allowed CEO Larry Page to step back from day-to-day operations to “focus on the bigger picture.”

Now, Alphabet is a massive corporation – ranking in size behind Apple, Samsung, and Microsoft – that encompasses everything from internet-beaming hot air balloons to self-driving cars to Google Cloud.

Here’s how all of Alphabet’s companies fit under the umbrella.

---

Google officially became Alphabet in October 2015 with the aim to allow its different businesses to operate independently and move faster. Each division has its own CEO, with Google cofounder Larry Page taking the helm of Alphabet.

---

There are several companies under Alphabet, but some bigger division include Google, which encompasses several different divisions, and X, which houses the “moonshot” projects.
