Neon signs are often placed in storefronts to attract customers. The very first display of glass tubes filled with colorful, ignited neon gas was meant to attract only attention, however. In 1910 at the Paris Exposition,
two straight tubes filled with lit neon gas were displayed to show off the new technology. It was not until
1912 that glass tubes were bent into a written message and put in the window of a barber shop to entice
people to come in

used to convey a written message

In 1912 Claude installed the first-ever neon advertising sign in a Parisian barbershop on the Boulevard Montmartre. A large rooftop sign for the Italian vermouth maker Cinzano soon followed, along with illumination for the entrance of the Paris Opéra. Ne or neon gas is used for advertising signs, as are other noble gases. ... The gas itself has no color until an electric charge is applied that alters the structure of the Ne molecules. Neon gas only produces a reddish orange color light, so other inert gases are used to make other colors.
