Comment Small ISP. (Score 2) 301
I used to worked at an ISP who had about 25 000 dialup subscribers. (And about 10 000 DSL) They were playing around with the idea of charging a couple more bucks for the service. I got asked to generate a connection usage report. Turns out 60% of the dialup customers had not connected to their service in the past 3 months. (That was 2 years ago, so 75% today would not surprise me at all)
When people are used to automatic billing either on their bank account or their credit card, they tend to forget that they're paying for some services they are not using.
