interesting. I don't know if there's an explicit standard but in the US the hot water is always on the left and the cold is on the right.

@123Daktary In the US there actually isn't a standard orientation for standard electrical receptacles. But since (most of) our plugs are non-reversible there's no way live and neutral should ever get mixed. Usually ground is on the bottom (and right angle plugs are usually designed with this in mind) but sometimes ground is up. Sideways receptacles are very rare except near Chicago.

In the US pushbutton tuning was never popular on TVs. Meanwhile on car radios there were almost always buttons for presets. I watch a number of radio restoration channels and I think I've only seen pushbutton band/function selection on European sets. For that purpose rotary switches were usually used.

Literally nothing was on the Mac long before Windows existed. There was barely a year between the release dates of the two.

@EwanMarshall The word "on" only works if it is next to the slider. If the word is on the slider it's ambiguous: does it indicate the current state or the state which will be selected when activated?

Round "porthole" TVs were a thing 75 years ago. Back when picture tubes were round most manufacturers would shrink the picture so the entire width was visible but this meant the top and bottom of the tube were wasted. Some manufacturers expanded the picture so the entire tube was lit but the sides of the picture were cut off. When rectangular picture tubes came out in the 1950s this practice quickly vanished.

The original interface was most common on old analog car radios where they were used for presets. You want to minimize time spent dialing in a station when you should be driving. Since old car radios were usually AM-only there was no need for a mode switch. In terms of implementation, oftentimes it was all mechanical, pressing the button would physically rotate the tuning knob through a few levers/cams/pulleys/etc. Sometimes it was interlocked electrical switches which would switch different tuning capacitors into the circuit. After car radios went to digitally controlled tuning in the 80s the implementation of presets was obviously greatly simplified.

If you ever put an American and a British person in the same room you'd learn that up/down on a UI toggle is a bad idea. We have differing opinions on which direction is on and which direction is off.

@stepannovotny4291 I've never been there but my understanding is their standard light switches are rockers with down==on. A Marshall guitar amp I had the chance to work on was definitely built that way. I occasionally watch UK electricians on YouTube and their breakers are up==on which sometimes causes confusion for homeowners. If there was ever a concern about things falling on the switch then down==off also isn't great. Because then if something falls then you get plummeted into darkness. Apparently in some earthquake-prone regions the standard is a sideways switch so falling items are less likely to flip them.
