Retro
Retro is a term used to describe fashions, trends and other cultural items that were popular or relevant many years ago. Generally, something that is retro is at least of  fifteen or twenty years of age. For example, a video game from 1997 could be considered as something retro. The term is especially used for things of the mid twentieth century (1950s, 1960s, 1970s and 1980s).
