Although there is no official "creator" alternative rock was a very unpopular underground genre for years until the 90's, when bands such as nirvana began calling themselves alternative, bringing the term alternative rock into the mainstream.
The term alternative rock came about in the very late 80's and 90's and at the time was synonymous with "grunge music". At that time there was nothing like it at all on the radio and in most places, in the very beginning, you couldn't really even find that type of sound even at a local bands show so it was an "alternative" to what was on the radio. As with most things who's popularity blasts off like a rocket, the scene became over exposed. What people call "alternative rock" today really isn't in the true sense of the term.
