* = The letter "A" was a toughie for the "TV & Documentary" category. There are many good TV series beginning with the alphabet's initial letter. It was a coin toss between the selected item ("The Andy Griffith Show") and such honorable mentions as: "Alfred Hitchcock Presents", "All In The Family", "Adventures Of Superman", "Adam-12", and any of the variety of "Apollo" multi-disc sets produced by "Spacecraft Films".
