Edie McClurg left the show during the third season for a full-time role on Valerie (1986). During the last two seasons her character was referred to off-camera, and largely replaced by Brandon's sister Ida Mae.
As Tiffany Brisette grew older, she and her mother often insisted that she be given more to do and evolve the Vicki character with changes of clothes, speaking in a normal voice, and singing. There was frustration over Brissette not being able to show any acting range. The writers would also campaign to switch up the formula of the show to keep it fresh, but creator Howard Leeds wanted to keep the show as it was.
The show was sold to more than 20 countries. It became quite popular in India and France. In Italy and Brazil, it was titled "Super Vicki."
