The games go under many names: Switch or Black Jack in England, Mau Mau in Germany, Mao or Bartog in the USA, Pesten in the Netherlands, Prsi in the Czech Republic, Makao in Hungary and Poland, Tschau Sepp is Switzerland, and so on.
There have been many commercial card games based on Eights but using sepcial packs of cards. The English game of WHOT!, patented in 1935, was perhaps the earliest of these; Uno is certainly the best known.
