I have never been aware of that, rather of the facts. Please visit:

for just a couple of references to what has actually taken place.
Three channel recordings were an idea to create a greater dynamic
response and to fill-in any space that was not complete as a result of
recording technicalities or listening positions. Even still, there was
only one "optimum" position for listening as is still the case for any
playback system independent of the head. When coupled with video, even
the head-mounted systems must remain in proper orientation until we
develop eyes eleswhere...

If by this you are resurrecting the 'we only have two ears so
we only need two speakers' argumetn, are you aware that the
first recommendations for optimal 'stereo' reproduction,
by the inventors of the format, involved using *three* front
channels?
