AOL reported solid second quarter earnings yesterday, revealing that it still makes most of its money from dial-up internet subscribers.

While the number of subscribers is dropping, the monthly price is increasing. According to re/code , 2.34 million people still subscribe to AOL's dial-up internet service, paying $20.86 per month on average. That number is down from the 3.5 million people who subscribed to the service in 2011.According to Seeking Alpha's reports, CEO Timothy Armstong is optimistic that the number of subscribers can grow again. "I think we are realistic that people are not buying access subscription at the access store that much anymore for dial-up ... As we improve the products there, I would sure hope that we get to the point where subscriptions are growing again, and that's our goal." The rest of AOL's profits come from display advertising.At one time, AOL's dial-up was a cultural mainstay, but it's hard to believe that 2.34 million people are still listening to the sounds of a dial-up modem connecting to the internet. Perhaps some people just forgot to cancel their service for the past fifteen years.
