It's a common thing to happen and I've noticed it a lot with middle age non tech crowds. It's not a new phenomenon overall but people talk about how their son made a YouTube or they sent a Gmail quite regularly. For some reason tech folks find it natural to use the verbs (e.g. I googled/youtubed it) but not the nouns.

It doesn't always require the service have 100% market dominance either, just that it be popular enough people hear others use it and commonly used in exclusivity by the user.
