Quiz drop for the day [Apr 7th]

In 1998 over a holiday X created his personal site and dedicated it to providing more information on the ebola virus. As the site evolved, one day he wanted to give away his broken laser printer and put up that in his site. When a customer bought it for $14.83, X called up the customer and asked him if realized that it was a broken printer? The customer replied that he was a collector of "broken laser printers" and this gave X an idea to change his site into Y.

As always, Identify X & Y :)
