Operation Prime Time

Background
Operation Prime Time (OPT) was a syndication block of programming created by the Organization to Promote Television, which offered to independent stations in 1976 by what was then called MCA TV (now NBCUniversal Syndication Studios). It was MCA's desire to launch new television shows by having them run in first-run syndication. In 1980, after the Paramount Television Service failed to launch, Paramount Television joined OPT, bringing with it Solid Gold (which ran until 1988) and, in 1981, Entertainment Tonight (which is still on the air, though it's produced entirely by CBS Media Ventures now). OPT's slogan was "for better programming". OPT and its successor company, Television Program Enterprises (TPE) were formed by Al Masini.

(May 9, 1977-1987)
Nicknames: "OPT", "OPT Rainbows", "Rainbow Lines", "Rainbow Pipes"

Logo: On a black background, four rainbow-colored lines, one coming from each side of the screen, come together to form the letters "OPT". The line from the left curves to form the "O", the lines from the bottom and the right combine together to form the "P", and the lines from the top and the right combine together to form the "T". When "OPT" is formed, the screen moves backward, as the words "Operation Prime Time" (in a rounded yellow font) appear from the right side and place themselves next to each letter. When everything is in place, the words "for better programming" appear in the bottom right hand corner. At the same time, you can see thin overlapping circles in the background.

FX/SFX: The lines forming the "OPT", the screen zooming backward, the company name appearing from the right. Like many 1970s logos, it's all backlit cel art and a few rostrum camera tricks.

Music/Sounds: A patriotic-sounding horn fanfare. In some cases, the last note of the jingle is very short, while sometimes it is longer. The Key to Rebecca had the end theme play over it.

Music/Sound Variant: Sometimes, an announcer says "An Operation Prime Time presentation".

Availability: Very rare.
