We have to think deeper as to why their service is the one that's preferred though. Part of it is the fact that they had historically been able to subsidize the monetization potential of their other services in order to out compete those who needed their services to make money. The other half is more speculation, but certainly very possible, that they've been able to play this game for a long enough time that they have been able to use search to build these brands in such a way that makes us think of them first for all of these services. Brand power is a very powerful thing, and considering the fact that they have a subsidized ability to advertise to us (both through promoting things in search, and by not needing to pay themselves for adsense/adwords) is what has made these the more high quality services over time since we have given our data to them.
