It was created by Roberto Gómez Bolaños (Chespirito), who also played the main character.  It was first aired by Canal de las Estrellas in 1970 in Mexico, and then was aired across Latin America and Spain until 1981, alongside "El Chavo", which shared the same cast of actors.  Both shows have endured in re-runs and have won back some of their popularity in several countries such as Colombia, where it has aired in competition with "The Simpsons" (which has a character based on him), or Peru.  The name translates literally in English as "The Red Grasshopper" (the word "chapulín" is of Nahuatl origin and applies to a Mexican species of grasshopper, while "colorado" refers to having conspicuous red colouration.  The word can also mean ruddy, reddish, red-coloured or crimson, blushing for instances would be said to cause the cheeks to be "colorados", and the skin would be "colorada" when you get a sunburn).  The main character uses a conspicuous red uniform.  It is also known in Brazil as "Chapolin", "Vermelhinho" ("Little Red One") and "Polegar Vermelho" ("Red Thumb") in allusion to the famous fairy tale character Tom Thumb.
