Mr. Pop History – Great question. After researching, compiling and documenting each week – from 1955 forward – I would have to say #1 is easily – MTV.

Although the channel borrowed from radio at first, it became a pop culture launching pad- for better or worse. MTV’s imprint is everywhere these days – from TV to commercials to movies.

What’s amazing is – it still continues to set trends. Just a few years ago (2006) – MTV did it again when it began the idea of presenting a pre-show before an event (The VMA’s).
