I want to say when King of the Hill got into syndication, around 2002-2004, between that period of time, when they double-ran KOTH at 10 p.m., that's when they ditched the news when Emmis was in a budget-cutting mood around then, along with the last years before John Chandik retired.
Another newscast change is WTMJ is getting rid of the 3 p.m. newscast as of tomorrow (the infamous 'sound-off', affiliate wire report and debate hour which seemed to only appeal to grumpy suburban shut-ins on the phone and Facebook) for FABLife; once WTMJ and the Journal-Sentinel were broken apart and they lost that five minute segment, along with the new Scripps management beginning to play down cross-promotion of Jeff Wagner's radio show on the AM side, the writing was on the wall (they claimed the decision was made before Scripps took over). Another thing in that JS article is that WTMJ is still in the process of finding a new anchor to take over for Mike Jacobs; most stations would have just given Steve Chamraz the job and moved on already.
