BBC Video (1991)

Nicknames: "Streaks of Doom", "Ominous BBC", "Dark BBC", "'90s BBC", "Possesed BBC"

Logo:

Opening: On a black background, a blue streak comes in from the right of the screen and a green streak comes in from the left of the screen. The two streaks merge to form a red line in the middle of the screen and they leave behind green and blue lines afterwards. The silver BBC boxes with white lettering, fade in above, forming a CGI version of the 1988 BBC logo used at the time.
Closing: Same as before, except the same copyright notice typeset from the previous logos in Futura fades in below the logo.
Trivia: This is basically the BBC ID from 1990.

Variants:

On the 1995 VHS release of the Doctor Who episode "The Five Doctors", after the logo forms it is snatched up by the Time Scoop (the device that kidnapped the Doctor's incarnations and his companions at the beginning of the story).
This variant is also included on the 2008 DVD release of "The Five Doctors," but as an easter egg. To find it, go to "Special Features" on Disc 2, then highlight "Nationwide" and go left.
Starting in 1995 on the copyright notice, "BBC ENTERPRISES" is replaced with "BBC WORLDWIDE".
Re-releases with this logo have the copyright notice in a different font (e.g. Helvetica or Gill Sans).
Starting in mid-1997, the closing variant has a different caption reading:
Distributed under license by BBC Worldwide Ltd.
© [BBC logo] (year in Roman numerals)
On They Think It's All Over: No Holds Barred, the closing logo had a different copyright notice reading:
© TALKBACK PRODUCTIONS LIMITED/
BBC TELEVISION
(year in roman numerals)
At the end of the 1997 VHS release of BBC TV Cooks - Rick Stein Cooks Fish, the copyright stamp below the BBC Worldwide disclaimer reads "© BBC Worldwide (year in roman numerals)".
FX/SFX: The animation.

Music/Sounds: A jarring and creepy 9-note piano piece that sounds like a pianist got possesed, followed by the sound of a choir holding the final note.

Music/Sounds Variants:

On the "Five Doctors" variant, an spinning whirl sound occurs where the Time Scoop steals the BBC logo.
At the end of the 1997 VHS of Diana: A Celebration (one of the last Tapes to use this logo), it is completely silent. This also occurs at the beginning and end of the UK VHS of the same Release.
On some re-releases, if you listen very closely, you might hear the faint 1984 music from the 1980 logo humming over the logo and warning screen, due to poor plastering.
Availability: Appears on VHSes of BBC programs from the era, like Series 1 of Yes Prime Minister. This logo is intact on the DVD release of Wallace and Gromit in Three Grand Adventures from DreamWorks Home Entertainment (around 2004). This weirdly also appears on Netflix prints of A Blackadder Christmas Carol, due to using a video master. It can sometimes plaster previous logos on re-releases. It appeared on UK Pingu VHS releases at the time ("Barrel of Fun" used the previous logo instead, though this logo appeared on the rare 1992 rerelease version)

Editor's Note: It's known as one of the more ominous logos in the logo community (with a scare factor of low to nightmare) due to its somewhat depressing music and black background, combined with the strange-looking BBC logo and limited animation.
