      It’s amazing that we don’t have to deal with this anymore for a lot of consumer electronics. Or someone running the microwave, disrupting an antenna signal.

        Analog TV were a lot more susceptible to electromagnetic interference (EMI) and would go all fuzzy.

        Old vacuum cleaners had motors that put out a lot of EMI, so every time someone in the house would run the vacuum the TV would start acting up. (Wasn’t just vacuum cleaners: any appliance with a big motor could, but they were usually far enough away from the TV to not be an issue)

        Better shielding on appliances and the switch to digital/LCD TVs that weren’t susceptible to that form of interference all but made that problem disappear.
