reading Adelaide's news. Prior to 27 December 1987, the presenters and production crew of 7NEWS Adelaide produced Ten News Adelaide (then known as Ten Eyewitness News). However, as the television industry was consolidating in Australia, these news services had each become associated by ownership with inter-state news services being broadcast on opposite frequencies; therefore, to simplify network interaction, their respective networks agreed to swap channel assignments and network affiliations in Adelaide. In December 2007, production of 7NEWS moved from studios located at Gilberton to a new purpose-built space at Hindmarsh. During the AFL season, Seven News Adelaide does not air at the regular time on Saturday or Sunday if there is a twilight match involving Adelaide and/or Port Adelaide, in which case, a shortened edition is broadcast at half time, replacing analysis of the AFL matches broadcast, or a full bulletin is broadcast immediately after the game. In 2014, 7NEWS Adelaide won every single ratings weeknight against the rival Nine News Adelaide, but in 2015 started to lose some nights to Nine as Seven News as a whole suffered its worst ratings figures for over a decade. It clocked up 500 consecutive weekly ratings wins in March 2019, extending a streak which started in August 2006. In August 2019, Jane Doyle celebrated 30 years of reading the news on Seven. In November 2019, John Riddell announced his retirement and presented his last bulletin on 6 December. Doyle became solo presenter after Ridell's retirement. In June 2020, it was announced that Jessica Adamson and Tim Noonan were made redundant. The weekday 4pm bulletin was also retired with Melbourne's bulletin broadcast to the Adelaide market. Rosanna Mangiarelli replaced Adamson on weekends. The bulletin was later reinstated on 26 October, but the axing affected Seven News in the Adelaide ratings, and helped rival Nine News to close the afternoon and evening news gap with Seven ever since. In September 2022, it was announced that FIVEAA's Will Goodings will replace Mike Smithson to co-host weekends. In November 2022, it was announced that Jane Doyle would retire from television after more than three decades presenting 7NEWS Adelaide. Will Goodings and Rosanna Mangiarelli were announced as her replacement, commencing from January 2023. Fill-in presenters include Mike Smithson, Andrea Nicolas, Elspeth Hussey, and Mark Mooney (News), Theo Doropoulos and Andrew Hayes (Sport) and Gertie Spurling and Casey Treloar (Weather).
