So here's the gist: Google has spun off Google, renamed itself Alphabet, which now owns Google. Google founders Larry Page and Sergey Brin will run Alphabet as CEO and president, respectively, while Sundar Pichai will run Google as its new CEO. Got it? Good. So let's talk about Alphabet.

In the announcement blog post and subsequent SEC filing, we have a somewhat vague idea what companies will be housed under the Alphabet umbrella. (There's also a new placeholder site, abc.xyz — alphabet.com is owned by someone else.) Not every letter has a company (yet), nor do we know where all of Google / Alphabet's pieces will fall (e.g. Google Auto). So without further ado, here are the companies that make up Alphabet's, erm, alphabet:

• Alphabet (the main company)
• B (possibly Boston Dynamics, but whether it's remaining under Google is unclear at this point)
• Calico (focused on longevity)
• Capital (investment)
• D
• E
• Fiber
• Google (now led by Sundar Pichai and includes search, ads, maps, apps, YouTube, and Android)
• Hooli
• I
• J
• K
• Life Sciences ("that works on the glucose-sensing contact lens")
• M
• Nest
• O
• P
• Q
• R
• S
• T
• U
• Ventures (investment)
• W
• X lab ("which incubates new efforts like Wing, our drone delivery effort")
• Y
• Z

Note: I am assuming Alphabet is using the modern English alphabet, based on the companies currently known. Therefore, I am listing all 26 letters, some of which are placeholders until Google announces / acquires a full suite of alphabetical companies (it has two C-businesses now, which means something's gotta give). If Google decides to use, say, the old italic alphabet or archaic Latin alphabet, I'll update accordingly.

If you want to suggest other companies that Google can buy to complete its alphabet, comments are open.
