Mail Call Letterpack – You get two players that play only the cartridges you can buy from Smith Corona and you can send a 3, 6 or 10 minutes letter. Just $70 a pair in 1967, these would be $450 in today’s dollars. How is this better than a phone? They say, it has no static and it’s cheaper!
Life, 1967
Make a 10 minute telephone call that will get to its destination in 4-5 business days, and in 4-5 business days you might get one back and can continue the conversation. Beats buying a reel-to-reel, and squelches telemarketers, too.
