The first illuminated characters, primarily created for big-city entertainment enterprises, consisted of electric bulbs arranged to form the outlines of letters. In 1910, the first illuminated letters – bulbs mounted in open metal channels – were mounted on the neo-Baroque pediment of the Corso cabaret theatre in Zurich. They were replaced by Max Bill’s linear neon type during renovation in 1934. Unlike a matrix type based on a grid, the points in BDot, are placed individually on an optical basis. Starting with the ExtraThin weight, the number of points is reduced by half for the following 5 weights. The centre of the dots remains in the same place, while they become larger as the weight increases through Thin, Light, Regular, Bold and ExtraBold. In the last two weights, they become a solid line with indentations. BDot has been created to complement BLine. It shares with it the same skeleton and the same width, making it easy to work in perfect tandem in print as in animation.
