Earlier quoted context omitted.
Although in this case Meta bought companies that were already established and successful. Google bought Android before it had released products. Google Maps was purchased, but was Where 2 actually a successful product prior to that?
I feel like you just cherry picked from my examples. YouTube was certainly successful - Google bought them because their own Google Video competitor was a flop. DoubleClick was also obviously huge. Where 2 had a successful product, it just wasn't web based (nor do I think free), so didn't have anywhere near the distribution that Google enabled once the team ported it to run in a browser.
You said
> buying a successful business and keeping it successful for over a decade.
Meta bought already successful companies.
Google has purchased successful businesses, but they also purchased companies that weren't and managed to get them into massive money makers.
