When I was young, you could still send a telegram. I don't think you can anymore. I'm sure nobody does. Western Union exists for the sole purpose of draining money out of the United States by illegal immigrants, who send it to their families in Bug Fuck, Egypt or where ever else they come from and need a reliable transfer.
Phone companies are going the same way as Western Union. They have peripheral businesses that may keep them around forever but I don't know anybody under forty that still has a land line or anybody under sixty that still uses one. My parents are in their eighties and are considering getting rid of their phone. Face it. You really don't want or need to talk to anybody you don't trust with your cell number. You never answer that land line. You don't even listen to the messages on it anymore. Get rid of it.
I'm fifty eight, I don't have any kind of phone. I talk to people over the interwebs, they never know the difference.
Don't buy phone company stock.
