followed on 6 September 1976 by the introduction of a new evening bulletin, the News at 545, which ran from 17:45 to 18:00; Michael Nicholson and Leonard Parkin alternated in the newscaster chair. By this time, with three regular ITN bulletins throughout the day – and each having their own look and specially composed music – the original ITN Non-Stop theme music was only seen on generic summaries and weekend bulletins. In 1982, it was finally replaced with a synthesised alternative. First Report was moved to 13:00 and retitled News at One in 1976; Leonard Parkin and Peter Sissons alternated in the presenter's chair. Michael Nicholson continued as main newscaster of the News at 545, with Martyn Lewis replacing Parkin as the relief presenter. In 1986, Nicholson left newscasting to return to war reporting and was replaced by Alastair Stewart. Leonard Parkin retired in 1987, and Peter Sissons became a main newscaster for ITN's Channel 4 News (before moving to the BBC in 1989) – it was at this point that the programme revamped. It was moved to 12:30, and appropriately became the News at 12:30. Julia Somerville joined ITN from the BBC's Nine O'Clock News to host the new programme, with John Suchet and Jon Snow acting as relief presenters. In 1988, the programme returned to its original slot and once again became the News at One; the presenting line-up remained unchanged. In 1989, Somerville left the programme to become a main presenter of News at Ten, leaving Suchet to become the main lunchtime newscaster – the programme was revamped once more. In 1991, the programme moved back to the 12:30 slot, but retained the studio setting. In 1993, graphics were relaunched to bring it in line with other ITN news bulletins. News at 545 was replaced by the News at 540 in 1989 (following the introduction of the ITV National Weather forecast), and a new presenting team was formed comprising Carol Barnes, Nicholas Owen, Trevor McDonald, Fiona Armstrong, and Alastair Stewart. The programme lasted until March 1992 when it was renamed and relaunched, in line with other ITN bulletins. News at Ten continued to rate as the most popular news programme on television. In 1988, the programme launched specially made opening titles featuring a computer generated travel through London, up the River Thames until the camera stops at the "Big Ben" clockface.
