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.
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.
