- lxgr 2y agoI've been wondering that too recently, and apparently it wasn't that big of a deal [1] – more recent analog TVs weren't that susceptible to mains interference of the sort that benefited from being synchronized to the frame rate. In other words, the mains frequency was never used as a frequency source for TVs, and the apparent frequency match was only to make interference patterns not wander around the screen.
