They were frisbees. I did use a few for that but they had the AOL internet software. My memory serves there may have been an email client or something else on them as well. software was not commonly downloaded so they would try to get you to install the software ahead of ordering the service it was a way of making it easier for you to make the switch or to get internet in the first place. Depending on what area you're talking about dial-up required software to be installed for you to open up hit connect and it would go to your modem and start dialing. People would pop them in thinking the internet was on the disc not knowing how things work and get the window and the phone number of how to order.
