Reo wrote the finale with series producer Judith D.Allison, and thus decided to make an allusion to the inspiration of the lead character.Reo had the utmost faith in NBC agreeing to the format as it was, and believed that the unique characters would transform family sitcoms if it became a series.NBC liked the screenplay, but ordered changes to the format.It began with Blossom's mother having left the family to pursue her own life and career, and focused on the family's attempts to adjust.Blossom's father, Nick, an overprotective, somewhat conservative session musician who was frequently between gigs and tours, who was played by Ted Wass.Network executives told Reo and Witt/Thomas that they wanted to see the lead character go from being the Holden Caulfield-like Richie to that of his older sister, Blossom, and that the girl should have Richie's character traits instead.At the same time, NBC felt that the combination of such an emotionally intuitive child and a super-chic father was too radical to put on the air, so they urged Reo and Witt/Thomas to give Blossom and her siblings nuclear, conservative parents.
Her father was played by Richard Masur, and was named Terry Russo; Barrie Youngfellow (fresh off It's a Living, another Witt/Thomas production) played Blossom's mother, named Barbara Russo.
Molloy faced low ratings, and Fox canceled the series after the seven-episode order completed.
NBC executives, who had been pleased with the ratings of the Bialik pilot special, ordered Blossom as a midseason replacement for January 1991.
In the Blossom series finale, the titular character records a new entry into her video diary, in which she discusses the changes happening in her life post-high school.
As she also examines how much she has grown since her first video diary entry at the beginning of the series, Blossom describes herself as "a teenage Holden Caulfield".
