While playing roommates on the show, co-stars Lisa Bonet and Marisa Tomei lived together in real life.
Originally, the character of Whitley was to only appear in the pilot. She became so popular that she become a regular, and made Jasmine Guy the star of the show.
Alfonso Ribeiro was originally set to reprise his role as Zach Duncan as a series regular. He chose to do The Fresh Prince of Bel-Air (1990) instead.
The show's popularity with young African-American viewers has been credited with boosts in enrollments at several real life historically African American colleges. A number of non African American students have also claimed that they were inspired to pursue a college education by the series as well.
Although Lisa Bonet and Cree Summer were never on the show together, they're best friends in real life.
