Fox Lab

Background
Fox Lab was a production sub-division of the Fox Broadcasting Company, originally following in the footsteps of Fox Televisions Productions. FTSP shut down Fox Lab in 2003.

1st Logo (1992-December 3, 1995)
Logo: Same as the Fox Televisions Productions logo of the time, but the text is replaced by "f o x l a b".

Variant: Sometimes only the first half of the logo plays.

Technique: Same as the Fox Televisions Productions logo.

Music/Sounds: None, or the closing theme of the show. It's said that there's a version with a one-note synth theme, but it hasn't been confirmed.

Availability: Extinct. The full version appears on America's Most Wanted: Final Justice. The variant was found on an early episode of What's So Funny?.

2nd Logo (December 3, 1995-August 24, 2003)
Logo: A -tinted gray tower structure pans down from above on a black background, revealing the words:

FOX LAB

written in the usual Fox font, with two static beams standing at the edges of the "L" and the "B" emitting sparks of electricity from side to side, then the structure rapidly zooms-out in its proper slanted "20th Century Fox" format position. The tower is now in, surrounded by a dark blue stormy sky, with a thick, bellowing, fast-moving mixture of cumulonimbus and nimbostratus clouds, (similar to the Fox Television Studios logo, only the cloud movement is faster and the clouds thicker and more defined). A jolt of electricity moves up the tower, similar to that of a "Jacob's Ladder". Sometimes, the byline "Times New Roman" fades in underneath.

Trivia: Like the other 1994 Fox logos, logo was produced and directed at Flip Your Lid Animation. More info here.

Variant: A short version of this logo begins from the zoom out.

Technique: CGI.

Music/Sounds: A dramatic choir-like sound with sparking electricity. On some shows, the closing theme will play over it. Otherwise, it's silent.

Availability: Extinct. It appeared on later episodes of What's So Funny? and the variant on the 2003 syndicated series Classmates, among other shows.
