Snow, on the television screen, after the end of the broadcast day. The radiant glow of projected Kodachrome imagery on a silver lenticular screen. The high-speed clickety-clack of a 16mm film projector, or the tack-tack-tack of typewriter keys hitting the page. The smell of warm Bakelite and the humming fan of an Airequipt slide projector operating. The looping, scratchy crackle of a record player needle after the record has ended. The fresh scent of newly printed purple mimeograph ink. The whirring crunch of a disk drive searching for data. The cacophonic ambience of a video game arcade. The buzzing, beeping, and dinging tones of a modem receiving data. All of these sensations, and many more, are now largely things of the past; memories and nostalgic recollections that my generation might be the last to have experienced as a part of normal daily life. Digital technology, for all its advantages, will never be able to accurately reproduce the sights, sounds, smells, and feel of yesterday’s analog technologies. The idea for this book began in 2015. For Valentine’s Day that year, my wife bought us an HDTV television set, to replace the NTSC cathode-ray tube television set that we had had since 2001, which had been a wedding gift. But having the HDTV set sitting in its box in the family room, waiting to replace the CRT, somehow made me realize the nostalgia I had for the old television technology, which was of course the kind I had when I was growing up. I realized it would probably be the last CRT we would ever own, and I became a bit loath to give it up. Ever-thankful for my wife’s patience with me, it wasn’t until October that we finally switched over to the HDTV, and of course I enjoy the high-resolution imagery and flat screen technology as much as anyone else. The old CRT now sits in the basement, my wife once again patiently waiting for me to get rid of it entirely, as its bulky shape takes up space in the playroom.
