> TCP was created in the mid 70's. The internet as we know it didn't offer the average user much value until the mid 90's and even then it was a very small amount of the population capable of using it / benefiting from it.

Using it directly.

I don't personally own any equipment that speaks ATM, but I benefit from the existence of networks that use that protocol all time.

Heck, I doubt I'll ever touch a Bloomberg terminal, and I'm not entirely sure if their existence really benefits me at all, directly or indirectly, but that doesn't mean financial companies can't easily find uses for them.
