While each of the first three seasons only had three episodes apiece, the TV series is very popular especially in its home country, the UK.
And unlike most TV series, “Sherlock” does not air yearly but every other year. Still, despite such airing pattern, it continues to draw in viewers. In fact, in the UK alone, its first season actually netted 8.82 million viewers. The figure grew to 10.23 million viewers when Season 2 aired early in 2012. Season 3, which aired early in 2014, got the biggest viewership ratings in the UK, with 11.82 million viewers.
Given its release pattern in its past three seasons, fans were expecting that “Sherlock” will air early in 2016. However, production for Season 4 of “Sherlock” has been delayed.
Showrunner Steven Moffat actually confirmed the delay when he said that filming for the new adventures of the greatest detective of all time will begin around April this year. Accordingly, the delay was caused by conflicts in the schedule of both Benedict Cumberbatch and Martin Freeman.
Cumberbatch just finished his Broadway stint a few months ago and he is now working for Marvel Studios to play the eponymous lead role in the upcoming film “Doctor Strange.” Martin Freeman was also busy with his other passion projects.
