Re: Back in the day
Some TVs & Radios had remotes in 1950s. One 1930s USA Radio had a WIRELESS connected dial to select a preset radio station.
I'm pretty common and I had email (300 baud or 1200/75 depending on if Prestel, BBS or X25 PAD) from 1981 on CP/M. By 1987 using an account to get access to Telex, Fax and Bitnet email from a PCW8256 with 300 baud modem. Fax replies were posted to me by physical mail.
