Piccadilly Circus was surrounded by illuminated advertising hoardings on buildings, starting in 1908 with a Perrier sign, but only one building now carries them, the one in the northwestern corner between Shaftesbury Avenue and Glasshouse Street. The earliest signs used incandescent light bulbs; these were replaced with neon lights and with moving signs (there was a large Guinness clock at one time). The first Neon sign was for the British meat extract Bovril. From December 1998, digital projectors were used for the Coke sign, the square's first digital billboard, while in the 2000s there was a gradual move to LED displays, which completely replaced neon lamps by 2011.
