It also changed the music industry in the sense that all of the original songs were in excess of four minutes. In the day, to get radio time, the general thought was that your singles had to be less than four minutes, really around three. It was from bands like Traffic that the new "Album Oriented" stations came about in the late 60s to early 70s and would eventually lead to the acceptance of songs like Zeppelin's "Stairway to Heaven" and Skynard's "Freebird" to reach the airwaves.
As an added note, Chris Wood died in 1983 of Pneumonia; some say it was related to his drinking. He was 43. Jim Capaldi died in 2005 of stomach cancer at age 60. Dave Mason went on to a terrific solo career as well as joining Fleetwood Mac on one album (Time) and currently performs with The Dave Mason Band. Steve Winwood continues to work on new material; About Time was released in 2003 as well as a possible album this year He has also been working on session sets with the likes of Sam Moore and Christina Aguilera.
