Not overly popular, but many people already knew him from the Bruce Lee era, so it had a following by default.
Same with Dallas and The Dukes of Hazzard.
Thinking WTR, Dallas, or TDoH are representative of American culture is... hilarious.
But I guess shows that hit the big American cultural stereotypes hard are maybe the ones that do better abroad?
It was just a fun show. Magnum PI, Different Strokes, McGiver.. were just as popular.
Oh and Married with Children, but it was always very late night and I was not allowed to watch it.
And our teacher always played us ET on VHS. (and that dog playing basketball.)
that's america for me when I was a kid
Exported media is weird. Like the huge proportion of British/BBC output (usually period, but also often detective in a way redolent of Christie) that is made primarily for export to foreign consumers who think of British upper-class culture as aspirational.
It was big internationally. But the jokes made Norris known to a whole different generation than the one watching WTR.
