ELI5: Why are dialects of English so similar even though English has a global spread while dialects of other languages (like German or Chinese) are so different they can be considered different languages, even though they're in one small geographic area?

Long story short: English's spread happened closer to the advent of technologies like film and radio that helped standardize pronunciation across time and space. This was only furthered by the "superpower" status that English enjoyed after World War II, where most films were in English, which served to quash or slow down divergence in pronunciation.
