Gmail is 15 years old.

Maps is ~15 years old (and was the combination of several acquisitions in the maps space: Keyhole, Where2, Zipdash, etc.)

Chrome is 11 years old + extremely successful, but my point still stands.

Plus Chrome is not really a product as, to my knowledge, it generates zero income.

Firefox and Safari generate tons of money for Google via search referrals so Chrome would have billions in revenue if it was valued the same way.

I believe it indirectly makes money as being a platform for Google's ecosystem, especially for their Enterprise Cloud apps suite or even Chromebooks.

Chrome is an advert delivery mechanism, if you see it from that perspective it looks highly lucrative.
