According to the Sitcoms Online News Blog, Ion Television will be expanded its weekend programming in early October by adding the 2PM and 3PM hours on Saturdays and Sundays. Previously, the network had aired paid programming from 2-4PM on weekends followed by movies. Beginning in October, movies will begin at 2PM with the occasional episodes of M*A*S*H and another sitcom, My Name is Earl, as filler when needed. Thus, M*A*S*H will no longer have a regular spot on the Ion Television schedule. In fact, based on the October schedule available here, M*A*S*H will air just once in October, on Sunday, October 24th from 1-1:30PM.
With M*A*S*H “resting” at The Hallmark Channel and more or less removed from Ion Television, that means only TV Land is still airing the series on a regular basis. Beginning later this month, it will be aired from 4-6AM Tuesday through Saturday morning and from 8-10PM on Saturday. The series also airs locally in some parts of the country.
