Why did the guitar become such a staple of modern music?

My grandfather was telling me that when he was a boy the guitar was seen as kind of an odd, out of place instrument that wasn't really played that often. Now it would be tough to argue that it isn't a staple of modern day music. A majority of bands follow a basic guitar+drums+vocals formula and while there is vast room for changes and additions, that is a pretty basic foundation. Why has this become so?

Guitar was popular in the 20's and 30's as a rhythm instrument for the most part.  (And for solo blues and country/folk and gypsy jazz and things like that.)  But most people wanted to see a Big Band with a full orchestra that they could dance to.

Then when big bands started to fade from popularity and electrical amplification started to take off, the electric guitar from Les Paul and then the Stratocaster from Fender were there at just the right time.

The electric guitar became associated with youth music in the early 50's and has remained so ever since.  But like Kwibbian_Kel's article says, it's not as popular as it once was.  But its versatility in widely different genres of music has kept it around for over half a century, and it will still be around for quite a while.
