This instalment recalls the 1970s, atime of new and scarier levels of branding and packaging of acts, from the Bay City Rollers to the Sex Pistols. MTV followed, further- and irreversibly-advancing the notion of music as product. With input from Simon Cowell , Pete Waterman , Rob Stringer and Nicky Chapman.
