In my opinion, it's really amazing how far technology has come. Adding onto this, considering how the world's first Internet radio show was being broadcast as early as 1994, it really shows how things were advancing rather quick.
In fact, reading these tidbits of information reminds me of a radio broadcasting show that I did a while back during my Senior year of college.
Though it requires a lot of experience, and though it could be pretty tough at times, on the other hand, it was pretty fun as well.
On a final note, if all of this was first broadcast in the 90's, it kind of leads me to wonder how some radio stations were able to play their songs, especially if they had to use the internet to do so.
