For the first time since World War Two, the giant illuminated billboards that have lit up London's Piccadilly Circus for over 100 years have been switched off for an extended period, as work starts to replace them.
The current six screens on the walls of buildings around the central London junction are making way for a huge, single, curved screen.
Due for an autumn unveiling, the new screen will display high definition video streams, show weather, traffic and sports updates and broadcast social media feeds from advertising brands.
In the meantime, a temporary banner will be installed.
The new space at the junction will be shared by six advertisers, including Coca- Cola, which has had its name up in lights there for 62 years.
