Longmire A&E has cancelled its western drama "Longmire" after three seasons. Robert Taylor and Katee Sackhoff starred in the drama which was the No. 1 scripted show in A&E's history. It will now be shopped to other networks. This month's season three finale averaged 3.7 million total viewers and a lackluster 0.6 key demo rating - a drop of 16% and 45% respectively from the season fine.
