The show gained higher ratings than the "Happy Days" series that had spawned it, at 4. However, the network management sought to improve the show in several ways. This was done in conjunction with what is known in the industry as counterprogramming, a technique in which a successful show is moved opposite a ratings hit on another network. The show was moved from Thursdays, where it outrated CBS's "The Waltons", to Sundays where it replaced the canceled sci-fi series "Battlestar Galactica". The show then aired against two highly rated shows: NBC's anthology series titled "The Sunday Big Event" and CBS's revamped continuation of "All in the Family" titled "Archie Bunker's Place". The second season saw an attempt to seek younger viewers and premiered a new disco arrangement of the gentle theme tune. The characters of Fred and Cora were dropped from the regular cast. It was explained that Fred went on tour as a conductor with an orchestra, taking Cora with him. Fred and Cora made return appearances in later episodes. Recurring characters Susan and Eugene made no further appearances after season one and were never mentioned again. New cast members were added. Among the new supporting characters were Remo and Jeanie DaVinci (Jay Thomas and Gina Hecht), a brother and sister from New York City who owned a new neighborhood deli where Mork and Mindy now spent a lot of time. Also added as regulars were their grumpy neighbor Mr. Bickley (who was seen occasionally in the first season and ironically worked as a verse writer for a greeting-card company), portrayed by Tom Poston, and Nelson Flavor (Jim Staahl), Mindy's snooty cousin who ran for city council. The show's main focus was no longer on Mork's slapstick attempts to adjust to the new world he was in, but on the relationship between Mork and Mindy on a romantic level. Also, some of the focus was on Mork trying to find a steady-paying job. Because of the abrupt changes to the show and time slot, ratings slipped dramatically (from 3 to 27). The show was quickly moved back to its previous timeslot and efforts were made to return to the core of the series; however, ratings did not recover. For the third season, Jeanie, Remo, and Nelson were retained as regulars with Jeanie and Remo having opened a restaurant. Nelson was no longer into politics and wore more casual clothes. Mindy's father and grandmother returned to the series.
