Even then, they can still be insanely profitable per engineer.
I think initially they only expanded to ~50 engineers until 900M users. Even today they are estimated to have only ~500 employees (no idea what percentage of that are engineers).
Engineering is listed as 25% of those 1823, operations 8%, education 6% and business development 6%.
I like "MAGNAM" if you include Microsoft.
I think Oculus is much more similar to Stadia than something else too.
Additionally, all of those platforms you mention du the same thing: chat and share pics.
Under the Google umbrella or alphabet is the same. Just like under Facebook or Meta.
Nobody cares about the exact legal construction of those products. Plenty of people still say FANG, where it's short for Google and not Alphabet.
Nice nitpick, but you obviously mispositioned your initial comment by putting the emphasis on household names and not on the legal structure, which is a strange argument fyi.
While I'm doing a low-content post, here's a tangential fun fact: the Latin sequence "gn" (as in, say, "magna cum laude") was pronounced with the G nasalized. If magna were rendered in English spelling, it'd be "mangna". (Or, well, "mongna".)
For things that are completely software, it does not surprise me that millions per employee in earnings is realized - that's just what happens when you operate at that scale. And that's accounting for all of the overhead in personnel that scale entails.
