Actually, when the Western and Eastern New England editions were broken up around 1979 or 1980, WFSB was listed in the (1) NY Metro, (2) Hartford/New Haven, (3) Springfield/Chicopee/Holyoke, (4) Worcester and (5) Providence editions. Then sometime in the mid/late-80s, the separate Worcester Edition was sort of annexed into the Boston edition, with not only ch. 3 WFSB but also chs. 22 WWLP and 57 WGBY from Springfield being added to the Boston edition for Worcester viewers as well. All three channels would eventually be removed from the edition by the early 90s.
So WFSB was carried in FIVE editions of the TV Guide...something not terribly uncommon in southern New England. Chs. 4 WBZ-TV, 5 WCVB and 7 WNAC/WNEV were all carried in the (1) Boston, (2) Providence, (3) Worcester, (4) Springfield/Chicopee/Holyoke and (5) New Hampshire editions in the early/mid-80s. I also know at times WBZ-TV has been included in the Vermont edition...not sure if that might have been the case at that time which would mean that it would appeared in six editions simultaneously.
WFSB-TV (CBS) channel 3 of Hartford, CT was in the Hartford/New Haven, New York Metropolitan, Springfield/Chicopee/Holyoke and Providence Editions. I think they even had a spot in the old Boston Edition (along with WWLP) back when Boston had a regular "Channel Listed In" page (before the cable conversion chart took it over).
