I've been an Eno fan my entire life, but I had no idea that he invented that sound. I wonder if he gets a royalty for every sale?
It reminds me of the "DUN DUN" sound from Law & Order, composed by Mike Post. I read that he's collected over $20 million in royalties from that sound alone.
When the guy who composed the song "Itsy Bitsy, Teeny Weenie, Yellow Polka Dot Bikini" died, I read that he called the song a "non-stop money making machine."
