Trolley Buses are over 100 years old as a technology. They were super wide-spread in the entire eastern block and now cities in hungary, the czech republic and romania introduce a lot of newer (better) models: For example, Skoda has one that can easily integrate with exsisting tram infrastructure and has batteries to bridge smaller distances in places where there are no overhead lines.

They're also fairly popular in China! When I was visiting family in Shanghai, a sizeable chunk of the bus service consisted of electric trolley busses.
