Well, Youtube is a stark counterpoint. Google today without Youtube is unthinkable. While I despise the company, Doubleclick also radically changed Google and was probably what changed Google into the advertising giant they are now.
True, particularly about double click, but is YouTube really a well managed acquisition?
It seems to be a victim of Google’s schizo approach to product in the sense that every 12 months it seems to be following a new strategy or launching a new product to replace an older one Id never used anyway. Their whole YouTube Red stuff, and YouTube Music, I have no idea what the long term strategy of this company is. Outside of ads of course.
Apple is just more careful on their acquisitions.
