TECHNIC is one of The LEGO Company's main lines based on creating detailed model machines and mechanical toys with specialized beams, axles, gears and connectors. The theme was first introduced as the Expert Builder series in 1977, but was officially renamed as TECHNIC in 1984.
1977 LEGO Sets
1977 introduced the Expert Builder series—precursor to Technic—using beams, axles, and gears for mechanically rich models. Town-style sets broadened everyday subjects with houses, shops, and vehicles. Dedicated Space and Castle themes were still a year away, but elements and styling hinted at their imminent arrival.
