LEGO 1997 / Duplo Sets

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.

1997 LEGO Sets

1997 saw LEGO’s first major sales decline, prompting experimentation and digital expansion. LEGO Island introduced the brand’s first open-world video game, setting the stage for future digital storytelling. New subthemes included Divers for underwater exploration, Fright Knights for gothic medieval fantasy, and Time Twisters as a sequel to Time Cruisers. LEGO Space added Roboforce and UFO, shifting toward alien-focused designs, while Aquazone expanded with Aquaraiders. Despite challenges, LEGO’s creativity remained strong across both physical and emerging digital platforms.
