Define Progressive

[Mike413]

It is my opinion that initially the term was used to describe bands who's music progressed beyond simple 4/4 time signatures and verse chorus song structures.

Somehow the term stuck and was applied to any arty band no matter how derivative they were. Not that this is a bad thing necessarily but I think these days too many people take the term "progressive rock" way too literally. To me it refers to a sound more than a musical approach that has to follow certain rules. Ultimately everyone seems to have their own definition of what is progressive or what is prog so there is no point in arguing about it.
