The first faux commercial record was one of the first real concept albums. Release in late '67 it would certainly not be Townshends last concept albums.

Wiki: The Who Sell Out is the third studio album by the British rock band the Who. It was released on 15 December 1967 by Track Records in the UK and Decca Records in the US.

A concept album, The Who Sell Out is structured as a collection of unrelated songs interspersed with fake commercials and public service announcements. The album purports to be a broadcast by pirate radio station Radio London. The reference to "selling out" was an intended irony, as the Who had been making real commercials during that period of their career, some of which are included as bonus tracks on the remastered CD.

The album's release was reportedly followed by lawsuits due to the mention of real-world commercial interests in the faux commercials and on the album covers, and by the makers of the real jingles (Radio London jingles), who claimed the Who used them without permission. (The jingles were produced by PAMS Productions of Dallas, Texas, which created thousands of station ID jingles in the 1960s and 1970s.) It was the deodorant company, Odorono, who took offence that Chris Stamp made a request for endorsement dollars.  "I Can See for Miles" was released as a single and peaked at number 10 in the UK and number 9 in the US.

The Who Sell Out has received widespread acclaim from critics, some of whom viewed it as the Who's best record. It has also frequently been featured on all-time lists of the best albums, including Rolling Stone magazine's "500 Greatest Albums of All Time". Full article
