There's also the factor that whatever show ABC puts in the 1 PM ET/Noon CT time slot most CBS and NBC stations are doing local news (At least in the Central time zone), so nothing they have had in recent years in that slot has done well. So whatever they put in that time slot may need to be considered as not having the best ratings but adequate to fill that time and hopefully do better than any other option or turning the time back over to the local stations.
