I do remember in July, 1979, when they split the Michigan State Edition, they turned the part that served my area into the Southern Michigan Edition for Grand Rapids, Kalamazoo, Battle Creek, Lansing ,Jackson and the Michiana area by South Bend, Ind. This was when WGN-TV and WSNS-TV both Chicago and HBO were added as was late-night only listings for WTCG/WTBS Atlanta. The following year it was split into the Flint-Lansing and Grand Rapids editions. The Flint_Lansing had WGN ,HBO and the late night WTBS listings plus now, ESPN and Nickelodeon,long before SpongeBob ,and the GR edition had not only WGN, WSNS,WKBD from Detroit,HBO and the late-night WTBS listings,but it added WTTW-Chicago and WTVS Detroit,both PBS stations, plus ESPN and USA Network. Then, after WSNS went to ON-TV programming in the Fall of 1980, full time WTBS coverage was added to the GR edition and the next year to Flint-Lansing. More cable channels were added to both editions before I left Michigan.
In Battle Creek, both editions were sold , as Meijer, K-Mart, Felpausch, Muir Drugs and Perry Drugs carried the Flint-Lansing edition, while other newsstands had GR, and in Sturgis,Michigan ,it was both the GR and Northern Indiana Editions, as the Northern Indiana one, had WGN as a broadcast station with more details on syndicated sitcoms on WGN.
