True, all that-- Designing Women's first go (1986-87 on CBS) had it likewise on DVD from Shout! (some episodes had the Coke Lady, some had CPE, and some had Sony).
I guess then that the DVD makers probably assumed that since TCFTV had a longer representation on the first two gos of West/Ward Batman, it would be like that all the way through-- they probably didn't figure on that fact that studio closing logos on television series change (and have changed)...
Why would the end titles on the third and final go of ABC West/Ward Batman (the Yvonne Craig "Batgirl" season, BTW) have a shorter TCFTV logo originally?
And speaking of such, the closing credits also have that remastered look, such that even a first-season episode (1982-83) could look like it was made in the 2000s.
