The music industry has changed dramatically over the past four decades. There was a time when guys like Ahmet Ertegun were founding labels like Atlantic Records, which was up and running before the birth of rock and roll. These guys were not marketing managers by education and were in business for the music first. Before rock was big $$ business record companies like Atlantic would sign relatively unknown bands like Yes and King Crimson (and Led Zeppelin too, though Page's previous band was well known) and have great success through these bands' respective album sales, regardless of radio-friendly singles. In the early 70's it was far more common for record labels to give artists creative freedom because they were not dependent on the album featuring a hit single in order to sell copies. FM Rock Radio in the 1970's was far more album oriented than anything you will find today, unless the station is an independent and hence not controlled by the likes of Clear Channel. Los Angeles featured a radio station KMET 94.7 FM (this station has been the Wave for the last 19 years, named after Yanni's waving limp wrists) that would regularly play tracks such as Supper's Ready by Genesis (KROQ once played this song too, in its first year on the air), and Siberian Khatru by Yes. These days commercial radio in the US is owned by a two or three companies and most programming is centrally directed at the corporate level. On the other hand, the nature of the record business itself is changing. Thanks to the availability of internet technologies to the masses, independent artists have more opportunities than ever before for getting their music to prospective audiences, at least those who aren't luddites! As such, music fans have more options than ever before in how they can obtain music, which is mostly a good thing. The methods for storing and purchasing music are also evolving. With said advances in digital and internet tech, the cd as the primary medium for how music is distributed is declining and the record companies, just about all of which are owned by 3 big international conglomerates, are changing the way they do business, notably by offering digital downloads of music they own the rights to. Lastly, the way artists do business with record and publishing companies is also changing. These days it is far more common for artists to negotiate deals that allow them to retain far more control over the songs they write than what was common thirty years ago. A good case in point here, and a fairly typical one, is Robert Fripp of King Crimson. His web journal over the past several years has often documented the battles he has fought in an effort to regain control of the publishing rights to music he wrote and recorded with King Crimson.
