The LEGO DUPLO theme was introduced as far back as 1969 and is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick. Like LEGO System, DUPLO also has subthemes that are often junior versions of System themes, like Pirates and Castle and licensed themes like Disney and Super Heros.
2010 LEGO Sets
2010 marked the debut of Collectible Minifigures Series 1 and 2, launching a global collector phenomenon. LEGO expanded its Disney partnership with Cars under DUPLO and Toy Story sets in minifigure scale, while Prince of Persia joined the lineup alongside Star Wars sets celebrating The Empire Strikes Back’s 30th anniversary. New original themes included Atlantis, Hero Factory (successor to BIONICLE), World Racers, and Kingdoms, a return to historically inspired castle play. Several older lines ended, including Agents, Bob the Builder, Indiana Jones, and Thomas & Friends.
