1st known (and possibly only) logo - (1980's)
Logo: On a black background, many green lines form, expand, and move to make a large, weird shape. A few seconds later, the words "MEGA VIDEO" spell, one letter every 2 seconds. After that, many white lines form, expand, and move to finish the shape.
FX/SFX/Cheesy Factor: All cheap CGI, with Scanimate effects. Also, the text spells really slowly and the logo is very long.
Music/Sounds: A flute sounder mixed in with some synthesizer notes.
Scare Factor: Medium. The theme is rather relaxing, but the shape is too weird, and the appearance of the text is extremely slow.
