and was replaced by Ray Martin. In 1992 Nine started the longtime slogan "Who's Who of News", using it right up until 2004. They continued to dominate until 2005. Seven, meanwhile, started to turn their fortunes around in 2003. They had picked up Nine's long-time chief of news and current affairs Peter Meakin and former Nine anchor Ian Ross to anchor the Sydney bulletin. By 2007, Seven News became the top news service around the nation and in every capital city in Australia. Beforehand, Seven News only dominated in Perth, in fact Seven News Perth has been the top rating bulletin in that market since the early 1990s. Since 2011, however, Seven started to slowly lose its nationwide dominance, partly attributed to the retirement of Ian Ross as anchor of the Sydney bulletin at the end of 2009, and declining ratings for the lead-in game show Deal or No Deal. Nine reclaimed its dominance in the Sydney market in 2011, followed by Melbourne in 2012, and then Brisbane (narrowly, by 21 weeks to Seven's 19) and nationally in 2013. Their dominance continued into 2015, when they also started to claim regular weeknight victories in Adelaide, where Seven had dominated for a long period. Seven, however, hit back in 2016, thanks to a new lead-in game show titled The Chase Australia, which helped to lift its news audience numbers on the east coast, where Nine continues to remain dominant.
