2012 is a year. Ninjago continued in a very snake-y manner, LOTR LEGO was introduced, LEGO Batman and Some Other Super Heroes We Hope You Don't Really Care About was released, and LEGO made a lot of money.
Another notable event this year was the end of the world. Doomsday occured on December 21, and Earth was destroyed. LEGO altered their marketing strategies in reply, but did not seem to suffer any massive loss of sales.
