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.
2015 LEGO Sets
In 2015, LEGO broadened its portfolio with new and returning themes. LEGO Dimensions launched as a toys-to-life crossover linking dozens of franchises including DC, The Lord of the Rings, and Doctor Who. New lines such as Elves, Jurassic World, Scooby-Doo, and Speed Champions debuted, while BIONICLE and Pirates returned in refreshed forms. City marked ten years under its modern branding, and Star Wars supported The Force Awakens with a major release wave. Meanwhile, Teenage Mutant Ninja Turtles and The Hobbit concluded as LEGO shifted toward newer properties.
