PRISM

Background
PRISM (Philadelphia Regional In-Home Sports and Movies) was an American regional cable television channel intended for cable customers in the Philadelphia, PA metropolitan area. Launched in September 1976, PRISM was primarily broadcast through area cable systems, although it was also available through a scrambled signal on WWSG-TV from 1983 to 1985. The channel's programming consisted primarily of theatrically released motion pictures, although it was most well known for its telecasts of sporting events. It was owned by various companies, and then it was shut down in 1997.

Logo: There is a mid-circle with 4 colors (green, yellow, blue and red) on it. Below there's various still yellow persons doing various things, with a white camera on the center. Three curvy zig-zag lines move on the center and start forming the word "PRISM", once it's finished, still yellow persons turn into different colors, making the final result.

FX/SFX: The lines forming the word.

Music/Sounds: A repetitive, warbly synth tune.

Availability: Extinct.

Editor's Note: None.

2nd Logo (1980-1982)
Logo: On a space background with a black surface, a prism is rotating and many lights come to it and the prism emits rainbows. The word "PRISM" emerges and moves on the center while the prism transforms into the mid-circle from the previous logo and moves to the top of the screen. The word glows in blue and shines.

FX/SFX: Scanimation is used to create the logo, and it looks good. Represents something like digital CGI, thus making it advanced for the time.

Music/Sounds: A majestic fanfare with synth sounds.

Availability: Extinct.

Editor's Note: None.

5th Logo (1990-1992)
PRISM (1990)

Logo: We see bendy transparent objects that look like I's wavering around and finally move into place, moving into a rectangle reading "PRISM" without lines. The I's go inside the rectangle, filling "PRISM" with lines. The rectangle moves downward, revealing a silver outlined "PRISM". A rainbow ray hits it and "PRISM" shines and is colored rainbow.

FX/SFX: Splendid use of CGI, holding up even today.
