1st Logo (June 18, 2004-October 28, 2005)
Logo: On a black background, we see the words "2121 PRODUCTIONS" in a strange, futuristic font appear by pixels with "2121" being bigger and on the word "Productions". The logo slightly zooms up a bit.
Technique: The words appearing, the zooming.
Music/Sounds: The end theme of the show.
Availability: Seen on the first season of Phil of the Future.
2nd Logo (June 25, 2005-August 19, 2006)
Logo: On a black and white background that has a liquid effect, we see the company name in the same fashion like before. The background clears up and turns black, similar to before.
Technique: The background.
Music/Sounds: Same as before.
Availability: Seen on the second season of Phil of the Future.
Legacy: It may catch those who expect the previous logo off-guard, but it's harmless.
