It was a day of comebacks and Melba imitations at the Seven and Nine Networks yesterday. Seven cleaned out its Sydney newsroom boss, Chris Willis, and replaced him with an old stager from 2GB and the Ten Network, Jason Morrison, and Seven also flicked its network news director, Rob Raschke. Nine brought back Daryl Somers into its 2016 line-up, ditched its weak replay service called Jumpin, and will continue with its fascination for Western Australia’s wealthy by turning the late Alan Bond’s life into a melodrama along the lines of the treatment given to Gina Rinehart earlier this year in House of Hancock.
