Did it ever stand for that? I know that that is what they wanted you to think that they stood for, but the truth was always to produce a TV Show that brought customers in front of their TVs in order to buy the junk that their advertisers wanted to sell. I don't want to think of the damage done by dynamiting sharks in one of their earlier TV Shows, or the senseless coral reef distruction in their searching for treasure TV Show. Cousteau was a whore who learned to give the customer exactly what he/she wanted to see.
After 20+ years of TV Shows, in the later 70`s, Cousteau discovered that there was a market for ecological shows, and he then jumped into that niche market too.
Untill he died, Cousteau was a showman, who had learned at a very early age that the best way to keep his pockets full of change and bed full of interesting women was to give the customer something that he/she had never seen before - kind of like the circus barker out front of the "fat lady's" tent.
