Re: Stop, just stop - search terms?
Unlikely to be that banal, but it could certainly be due to something like the CS course requirements being revised in say India to include a mandatory course in assembler 101. That would generate a lot of artificial popularity, just like Scheme and Logo were "popular" 15 years ago (I love Scheme BTW, no intent to disparage it here).
In any case the point is that the TIOBE "ranking" is entirely disconnected from reality, both in the professional world (as can be seen on any job board, e.g. Monster, Indeed) and the enthusiast side of things (as seen on Github and in game modding communities) and should not be taken seriously by any IT journalist worth their salt.
