When was the last time you heard a dial tone? When was the last time you used a rotary phone? Or a pay phone?

I tend to use Siri a lot. I don’t go to my phone app, I just ask Siri to call the number for me. And I call people a lot less than I text them.

We’ve come a long way from a family phone being connected to our wall, with a long cord attached to the handset. We’ve moved the phone from a side character to the protagonist. From an item to occasionally connect to one person to a tool of constant contact to the world.

Along the way, the idea of the dial tone disappeared. What else has disappeared?
