I believe it had the origin in a legend that some guy in the old web sold ad space on a 1000x1000 px canvas for 1$ per pixel and got rich with it. Not so much a "legend" as an easily verifiable known thing that happened which is still online. https://en.wikipedia.org/wiki/The_Million_Dollar_Homepage
