All Third Watch fans will probably be interested in this; The series has been canceled - Permanently - by A&E.
According to A&E officials, their contract with Third Watch has expired and is not being renewed. Therefore, A&E has lost the rights to air any Third Watch episodes, which prompted the show's cancellation.
So far I have not been able to locate any Third Watch programming info for any other networks/channels.

I have been a long-time fan of Third Watch and faithfully watched the show every weekday on A&E.

If anyone knows of any networks/channels that have picked up a contract with Third Watch and has plans to air it, please advise me.
