By that reckoning any energy recovery line output stage is a switchmode PSU.
If you want to draw the distinction between regulators and direct mains powered supplies that may be trickier. Any energy recovery line output stage running more or less directly off rectified mains would count as the latter. Whereas the IE DS 5050 I referred to earlier has SM regulators.
I don't know when computer makers turned to SMPS. They needed lots of amps at accurate and stable low voltages long before most of us.
