I think Ninjago is actually a top contender for the longest running LEGO theme, because most Castle and Space subthemes lasted 3 years at the most. (even though most of the subthemes of each theme were connected in the 80s/90s)

By the way, Classic is a recent theme that was introduced around 2015, you might be confusing Classic with BASIC. Yes, but City is still about two years older than Ninjago. Lego Minifigures was introduced in 2010 and it's still running. And of course there are Duplo, Techinic and other "basic" themes existed since tze 70s and are still running. The previously mentioned themes will probably take as long as LEGO remains.
