The BBC have confirmed the third series of Sherlock will début on New Year's Day, exactly as the second series did back in 2012 (but does this mean it's airing on Wednesday evenings for the entirety of its three-week run?) American viewers will have to wait almost a month, as PBS won't broadcast it until 19 January 2014.
Fox UK have also announced their plans to reduce the gap between US and UK broadcast of The Walking Dead. Currently, British fans wait five days for a Friday night premiere, but Fox UK will begin showing episodes on Mondays (the day after their US début on AMC). I'm not sure what has encouraged this change, but I'm sure piracy has a lot to do with it. Or to protect the audience from spoilers? It'll be interesting to see if Fox UK see an upswing in ratings next year, now Brits only have 24-hours to wait—as Sky Atlantic treat Game of Thrones.
