LEGO City, originally known as (and also currently alernatively known as) LEGO Town is a series of construction toys by LEGO, consisting in playsets with a modern, mostly urban settings, also divided in many sub-themes. It's one of the three original Lego System themes along with Castle and Space
The series was renamed four times through the years:
Town Jr. (1997-1998), a reboot to the series featuring simpler sets.
City Center (1999-2001). Known as City in European countries.
World City (2002-2004)
Some people consider the new names sub-series of the general Town series, rather than renamings of it. Both versions are right to some degree. No Town set was released outside these new series after their creation (Aside from sets that are part of other subseries), meaning that is right to consider them replacement for the original series, however these names were introduced to better identify those sets that wouldn't be part of any sub-series, since were general "town" sets, so it's debatable if the renaming should be applied to the whole town series, or only to those sets that aren't part of other sub-series.
A very high number of toy sets were released, some of which are part of specific sub-themes.
