Difference Between Surround and Stereo

I got my first surround sound system before Home Theater and surround sound were a common commodity. In fact I was looking for a new TV at the time and I liked of the Sony models and it had surround sound ability with the speakers and the whole deal as one package. I wanted to get the high quality screen but once I heard the sound, it was a done deal.
