Google has been screwing up EVERYTHING lately. Every recent Google product launch that I can think of has been botched. They're REALLY checked out over there.
Serious question. What's the last major successful Google project that was built within Google and not acquired?
I can't think of one.
Edit: Also Google Home devices, especially the Mini
No friend discovery, funded by ads, people mostly ignore emails I send them, but everyone has it and depend on it being rock solid. It's like air.
If my "major" you mean "more than 100MM users", it's been a while, but then what was the last (new) product launch by any established company that has 100MM users? If you drop that to a smaller number, there are tons though.
If by product you mean "consumer product", again, perhaps a while, but I'd argue that there are tons in the business space. (ML, cloud, etc.)
