According to Hallmark Channel’s online schedule M*A*S*H will return to the cable channel on Monday, October 19th with a three-hour block running from 5:00PM to 7:00PM featuring the first six episodes of the series. Here‘s a static version of the day’s schedule. Last Monday (October 5th) both Hallmark and ION dropped repeats of M*A*S*H from their schedules but it appears Hallmark has either had a change of heart or always planned to bring back M*A*S*H (it will not be back on ION).
Based on Hallmark’s schedule for the rest of October and the first week of November it looks like M*A*S*H will be shown Monday through Friday from 5:00PM to 7:00PM for the foreseeable future. Thanks to Alice for bringing this to my attention.
