When I was a kid, I used to watch this show a lot.
In Indianapolis, I remember Small Wonder airing on WTTV at one point (I think the first season) before moving to WXIN.
In Dayton, WDTN aired the show Saturday evenings at 7:00 for a few years before moving to Saturdays following the ABC Saturday morning block. WDTN also aired the show for a number of years--into the mid 90s--following its original run Saturday mornings before the ABC kids block.
In Cincinnati, WKRC preempted one of the Friday night ABC sitcoms to air Small Wonder (I'm pretty sure it aired at 8:30 during the course of its run).
