Remember telephones? There has been such a shift away from using them that many companies discourage calling. Email promotions are sent without including phone numbers for more information. You need to click through the contact page of some web sites to find a phone number.
The irony of this, of course, is that the smart phone is the dominant communication device and it’s used far more for other things than for talking. Curiously, making calls is the fifth most used app on a smart phone.
