When the heck did .NET took over????

I was looking at job vacancies and all of them all said to the point of must have exp in C# or ASP (for web programming).

When the heck did Microsoft took over??? I though C++ and PHP were reigning still.

C# is the only language that can do true OO

You gotta be yanking my leg. If somebody tells you that, they've just shot their credibility to hell.
