I went with some friends on Thanksgiving to a bar I never was at before. The bar's landline phone was ringing often, I guess people wanted to know if they were open on the holiday. Anyhow, we were watching football on their tv, and everytime the phone rang, the caller's phone number appeared on the TV screen. Below the phone number it either said their location (city or town), or else it showed the name of the cellular company.
I never knew such a thing existed. How the heck does a phone number end up on TV? That seems really bizarre. I asked the bartender how that works, but he said he did not know. I did find out their tv signal is from a satellite dish but that's all I know.
Has anyone ever seen such a thing? How does it work?
