Gracie Films/20th Television (1990/1994)

From The Simpsons episode "The Telltale Head" (S01E08), captured from Channel 4 in 2020.
While most episodes from the first 3 seasons of The Simpsons had the TCFTV logo plastered by the 1992 TTV logo, a couple episodes, such as this one, had the later 1994 logo instead.
And yes, this theme did debut in 1994, on the X Files.
This is a reupload of a previous capture to fix the original video being poorly cropped.

Takes me back to watching Simpsons episodes growing up on Channel 4. Don't remember seeing the 20th TV logo to often but memory is a bit fuzzy

20th Television only really appeared up until the end of S6, everything after would be TCFTV.
