1st Logo (1980-1990)
Logo: On a teal gradient background, two cards that feature a sun-like object and the letters "E" and "O" slide in. After that, they open up into a box, then some blue and green stripes move into the box, then come to the top of it. We see that the box made of the cards are gone, and the stripes come together and become the EO symbol (the blue stripes becoming a circle and the green ones becoming an abstract "E" that looks like a reversed "3"). Before that's done, the background turns black and a light rises in the center.
FX/SFX: 2D animation that just GOES back into the 70's.
Music/Sounds: An orchestral fanfare that becomes more powerful.
2nd Logo (1983-1990)
Music/Sounds: A calm, orchestral fanfare.
3rd Logo (1990)
FX/SFX: CGI animation.
Music/Sounds: A calm piano tune.
4th Logo (1990-1991)
FX/SFX: CGI animation
Music/Sounds: A remix of the 2nd logo with a piano, synth drums, a synth horn, a background choir and Violins, ending with a synthesized ping.
5th Logo (1991-1996)
Logo: We see the new EO logo (a rounded rainbow "E" with a blue "O" inside it) rotating as it travels against various searchlights, with the camera panning with it. As the logo travels, we see some live-action videoclips in the searchlights. Then, the logo goes through the lights and faces us, with the lights disappearing.
FX/SFX: Simple but good CGI.
Music/Sounds: A slow, uplifting fanfare with french horns at the start, an electric guitar, a trumpet and synth beats.
Availability: Extinct. The station no longer existed at this logo's end date.

7th Logo (2003-2004)
Music/Sounds: An upbeat 4-note jingle or the closing theme of the show
