Most of the seeming analog controls on cars switched to digital in the 1990s. The digital control bus saved several hundred dollars per car. It still looked analog until around 2010 when touch screen started taking over.
Probably in 2010 the price of the touch screen began to out compete the price of the analog controls on the bus.
