90210 with Friends being a close second.
My first choice would have been JAG.
Yes, it was called Beauty and the Beast (assuming you mean the show with Vincent and Catherine.) That was one of my mom's favorites, too.I loved 90210 and Melrose Place...! I didn't really watch Friends until it was into reruns...my mom was big into Dr. Quinn....and not sure if it was in the 90's (just googled - was 87-90)but she loved Beauty and the Beast (was it called that) as well!
2 that don't appear in the poll -
Seinfeld - I LOVE LOVE LOVE that show!
