A closer look
The chemical element neon was discovered in 1898 by a pair of British scientists. But it wasn't until the early 20th century that its commercial applications grew.
Neon, sometimes combined with helium and argon gases, would radiate light when electrons were "excited."
Neon signs first appeared in Paris around World War I, then were brought to Los Angeles in 1923 to light a Packard car dealership in the mid-Wilshire Boulevard area.
Neon came to Las Vegas in 1929, with a number of small projects over the years. The first major neon sign in Las Vegas was the Young Electric Sign Co.'s project for the Boulder Club, unveiled in 1954.
