Flashback to the days when literally every MS product had “.NET” shoehorned into its name somewhere because they had to show they were hip to this newfangled information superhighway thing. The development platform that still has that name 20 years later was just one of a zillion confusingly named marketing initiatives back then.

Edit: Wikipedia sums up the "failed branding campaign" quite scathingly: https://en.wikipedia.org/wiki/Microsoft_.NET_strategy

I think that campaign followed on from everything being named "Enterprise" something. I still miss the days when SQL Server Management Studio was called "Enterprise Manager"...
