I remember in the early days, you HAD to put the WWW. in the address.

Now a days, you don't. What happened, or changed?

A few years a go at school, I over herd someone talking as I walked by. Not sure what exactly he said, but I think it was something like, "3rd tear internet we don't have to put the WWW. in." (What ever 3rd tear internet is)
Like I said, I was just walking by and may of not heard him right, or even about what he was talking about.

So, what happened to having to put WWW.?

Thank you for the reply's,
Chris.
