We mostly watch news and sports in my house. So unfortunately, live TV. Occasionally we watch other things. I mute the commercials and browse my phone when they’re on.
But I would love a TV that is smart enough to auto hide & mute every kind of ad. Even little logos on the athletes’ uniforms. Hide the ads on the pitcher’s mound. Hide the billboards and signs in the stadium. Show some cool little generic animation, music video, or slide show during commercial breaks. Hide the damned popup window ads and scrolling ads that some channels do. Remove product placements from movies and shows. Basically make all ads completely vanish.
Or, and hear me out, you could say “portable fax” and be done with it. YOU are making it complicated by not being culturally acclimated to the timeframe when it was written. Everyone knew what faxes were, no explanation was necessary.
Portable fax: thing that sends and receives messages
Portable Fax IS how you describe SMS in the 80s.
I dont mean that your understanding is unimportant, but that you inherently understand what’s being described to a degree that to hear it described differently than you expect you reject what you hear in favor of assuming the folks in the 80s needed more than “portable fax” to understand what you are on about.
Pagers were in somewhat common use in the 60s, by 1980 wide area paging was on the market offering the ability to send text messages to portable devices anywhere in the country - I’d describe sms as two way pagers.
That’d work, but Sagan opted for portable fax.
