📺 Showa Trivia: 'TV Static'! The 'beep' that signaled the end of broadcasting, quietly closing the day

Life without a remote control on the low dining table

The living room at night. Orange peels on the low table, steam rising from a teacup.
The TV was in the center of the house, and you changed channels by turning a dial with a 'click...'
After the program ended, the screen would turn into static, and a 'beep' sound would linger in your ears.
When that came on, sleepiness would strangely take over.

Static wasn't a 'malfunction,' it was a feature of the era

By today's standards, you'd think, 'Is the signal bad?' but in the Showa era, static was just the 'natural scenery' after broadcasting ended.
Depending on the station, a 'Broadcast Ended' caption or a test pattern would appear, eventually leading to static.
In other words, static was like a silent chime telling the TV, 'That's it for today.'

As for trivia, there's a story that the 'beep sound (such as the 1kHz reference tone)' was a remnant of its role in technical verification and adjustment.
Even if it was just an annoying sound to viewers, the 'culture of tuning' behind the scenes of broadcasting was faintly seeping through.

This was usually the point where children would fall asleep

Parents would finish watching the news, there were no more programs, and the static would arrive.
'Alright, time for bed.'
Even when told that, children wanted to stay up until the very end. But the static was powerful.
The screen wasn't moving, but the sound alone pierced through, making eyelids heavy.
That moment had a certain 'aesthetics of defeat,' where you'd retreat to your futon on your own before getting scolded.

And sometimes, no matter how much you turned the dial, there was only static, and it felt like the whole world had fallen asleep, which was a little scary.

In an era where you can watch anything anytime, that 'forced shutdown' no longer exists

Now, with streaming, you can watch as much as you want even in the middle of the night. It's convenient, but I feel like the Showa-era 'TV ending' served as a boundary that helped us settle into sleep properly.
The static was noisy, but when I remember it, it feels strangely warm.
I suppose that was the sound of a family's day quietly coming to a close.

This is a series that nostalgically digs up the scenery of the Showa era. I would be happy if you could like and follow.
