From a technology-and-society standpoint, I find it fascinating:
When long-distance phone calls were rare because of their expense —anecdotally, well into the mid-20C (1970s?) for most Americans — getting one made your pulse race because it likely meant a birth, death, or serious illness/injury involving someone close to you. Telegrams — again, anecdotally — seem to have worked that way for my parents (b. 1926) as well, but that may have been a specific effect of WWII-era “We regret to inform you . . .” messages.
I was remember, growing up (b. 1963) being very clear that “routine” news from far away, good or bad, came in the form of written text . . . that is, by letter.
Perhaps the use of voice (rather than writing) as the default communication channel for people not in the same space will turn out, like the retailing of popular songs in groupings called “albums” (rather than individually), to have been a tech-driven historical anomaly . . .
