We 'dial' a phone number, although rotary phones have been obsolete for years.Its similar to how we call the automobile a "car". Car came from the word carriage which is what everyone was used to calling a thing that took you somewhere other than walking.
We could have called the the internal combustion driven horseless carriage, but "car" was easier.
We dont call our TV's televisions much, and now they are basically monitors, but we call them TV's still.
I call my devices APV's. I used to just call them PVs, but too many people "hear" that as TV. As in, "Where is my PV?" ... "Your TV?" Adding the A to APV eliminates that confusion.
