TTY allows hearing impaired individuals to make and receive text phone calls.

TTY (http://en.wikipedia.org/wiki/Telecommunications_devices_for_the_deaf)

It's still being used to communicate via land lines with people who speak but texting is taking over. I worked with a completely deaf guy at work who texted like a fiend. He loved text messaging because he "could finally use a cell phone like everyone else." It really meant a lot to him.
