The most successful language in the last twenty years.
Arguably, that would be Java, which was introduced in 1995. For whatever hey are worth, most language popularity indexes (TIOBE, LangPop) place Java above Python with quite a large margin. Java may not get much exposure here or in startups, but if you go out in the real world of 'boring' business applications, Java is pretty much the defacto language (together with C#).
