When Thames Television lost its franchise in 1991, Carlton Television was appointed the new ITV weekday contractor and collaborated with London Weekend Television to set up a unified, seven-day news service for the city.
 
London News Network, also known as LNN, went on air from 1st January 1993, the same day that Carlton replaced Thames on air. LNN was based at the London TV Centre on the South Bank, also home to LWT. A view of the City skyline dominated by St. Paul's Cathedral, was visible through the window in the main news studio.
 
LNN presented several bulletins each day, including the flagship London Tonight. Meanwhile a factual division produced documentaries for the region. London Today and London Tonight are still on our screens, but since 2004 they have been produced by ITN. By this time, Carlton had merged with Granada - the parent company of LWT - to form a single ITV network company. The ITN facilities on London's Grays Inn Road now play host to the news service, but the riverside skyline backdrop is maintained on a plasma screen behind the presenters, courtesy of a live video feed from the South Bank.
