Historians tend to forget that the 1979-80 Saturday Morning season was delayed by a couple of weeks for reasons largely unknown (the writers strike hit the following year). ABC, needing to fill time, decided to experiment by showcasing one of their first year primetime sitcoms.
Out of the Blue was the latest to come from the Miller/Milkis/Boyett stable, which at the time was associated with Paramount, and had slight ties to one of ABC's top sitcoms, Happy Days. Emphasis on slight.
Blue actually had more in common with Mork & Mindy, which was beginning its 2nd season. In fact, Mork himself (Robin Williams) made a guest appearance on the opener, and seemed to be plenty familiar with Random, an angel sent from Heaven to watch over a family. Mork greeted Random with the line, "Hey, brother! Sell me some wind!", which I thought was pretty funny. Unfortunately for Random (Jimmy Brogan), he couldn't rely on Mork to help bring the laughs on a regular basis, and Blue was given a quick hook from the primetime lineup.

As I noted, Random had also appeared on Happy Days in order to prevent Chachi (Scott Baio) from selling his soul to the devil. It was just one of those deals where they had gone to the creative well one time too many. ABC would've been better off keeping Blue on Saturday mornings after all......
