Business card CD ROM's were a nice idea in the day.....

.... trouble was they would often 'misfeed' when using a tray style CD Rom drive and jam in the mechanism, meaning you had to dismantle the drive to get the card out.

Understandably, this would quickly piss off people you gave the card to. This helped make the cards rather unpopular.
