That's ok.

They most definitely were, it is just that you are not aware of it. There runs a direct line from the 1-900 phone industry to the internet adult industry, those guys had money like water and they spent a fortune on these developments. Not all of them worked out but quite a few of them did and as a result those very same characters managed to grab a substantial chunk of early internet commerce.
