Before there were any LEGOLAND Parks anywhere in the world where LEGO could demonstrate the endless possibilities of its toy bricks, the company thought of another way to show what you can make with LEGO: The LEGO Road Show. The first LEGO Road Show takes place in Dayton, Ohio in the United States in 1978. Later this will be renamed to LEGO World Shows. The first LEGO World Show is in Denmark in 1981.
