Building Sets are the plain DUPLO brick sets, buckets and boxes of bricks without a story. DUPLO started in 1969, and the name comes from the Latin word for double, because each brick is twice as long, wide and high as a LEGO brick. The studs are made to fit, so DUPLO and LEGO bricks lock together and a builder can move from one to the other. For years the plastic bucket was the usual way to sell them, from the 1980s through the early 2000s, often shaped or printed as an animal, a farm or a circus, and some came as anniversary editions. Later sets switched to cardboard brick boxes with ideas for what to build on the side.
2011 LEGO Sets
2011 introduced Ninjago, which quickly became one of LEGO’s most successful original themes and the foundation of a long-running multimedia franchise. Other launches included Pirates of the Caribbean, coinciding with Disney’s On Stranger Tides, the sci-fi Alien Conquest, and Master Builder Academy, a design-focused building program. LEGO also experimented with digital-physical integration through Life of George, an early augmented reality experience. Collectible Minifigures Series 3–5 strengthened LEGO’s growing collector market, while internal employee-exclusive sets like Moulding Machines became prized rarities. Several themes concluded this year, including Harry Potter, Ben 10, Power Miners, Toy Story, Prince of Persia, Space Police III, and BrickMaster.
