Go back into 1915, exclusively a hundred years ago, there clearly was no online, no tv, zero broadcast. There were phones plus it was feasible to deliver one telegram, however it is costly plus unusual for most of us to do so often. People mainly penned letters in order to communicate. In the event that you desired understanding, you had to go to the library or inquire someone. Alternately, you may have to call home because of the proven fact that there clearly was one question that you might perhaps not answer.
