I just want to say that I love how the response to this comment is several lists of 4, with search being the only one present in all of them.

The 4 I was thinking of:

Search, Maps, Gmail, YouTube

Chrome is arguably a monopoly if you segment desktop web traffic, but iOS Safari is such a large percentage that Safari can't be ignored.

People will disagree with email - but I challenge you to go look at email threads you're on and see what % of the emails are @gmail.com - not to mention G Suite addresses you don't know are Gmail. Outside of enterprise, there's no alternative.

Not bad either that Android and Chrome are duopolies at this point.

Search, Maps, YouTube, Chrome. (They all have competitors, some more successful than others.)

A bunch of people have listed Gmail on their lists, but Gmail is not even close to a monopoly, even in consumer email. https://email-verify.my-addr.com/list-of-most-popular-email-...

I have 2 remarkes:

- that's from 2016

- that seems to be worldwide (I see for example swiss and french providers in the list), which isn't necessarily relevant. Gmail can be a monopoly in the US for example, while not being one worldwide.

Unfortunately I cannot find better numbers, if someone does that would be interesting to discuss.

I actually don't think Gmail (as other comments here claim) is nearly as much "monopoly" as YouTube. There are many email providers, people use whatever.

If I had to guess what GP is referring to: search, maps, email, and browser.

While I'm sure we could disagree on if Google actually has a monopoly in these domains, I think it's obvious they have a _substantial_ foothold.

Pretty much! https://news.ycombinator.com/item?id=23632044

I would say: Search, Map, Translate, Gmail.

Though technically they also have YouTube and do monetize it.

Search, the browser, email, non-streaming video are the only things that come to mind.

Search, Email, Maps (they own Waze), YouTube

Search, browser, email and maps.

search, maps, mail (gmail), video (youtube).
