The news service was produced and broadcast from Thames TV's headquarters at Euston Road in north-west London and, during its last few years in operation, from district newsrooms in Dartford in Kent, Guildford in Surrey and Watford in Hertfordshire.

Instead, Thames produced Today, a local current affairs magazine show presented chiefly on alternating nights by Bob Holness, Eamonn Andrews and Bill Grundy.

Today was replaced on Monday, 12 September 1977 by Thames at Six, a more conventional news magazine programme, presented by former ITN newscaster Andrew Gardner.

The following year saw Thames establish a full strength newsroom, enabling daily coverage of London-specific news for the first time in ITV's history.

A late night bulletin, broadcast after News at Ten, was due to launch on the same day, but was held back until Monday 28 April 1980 because of union problems.
