Dolby Surround

1st Trailer (Still variants) (1975-2002)
Logo: Superimposed in the closing credits of a movie or a show is "presented in" in Arial Italic font. Below it is the "DD" Dolby symbol and next to it is "DOLBY SURROUND" in a box. This may not count as it's just part of the credits, whereas the ones below aren't.

Game Variants:
 * The logo on Druid is revealed by light and the shield appears to be, but the next second it opens at full view and becomes golden with "SURROUND" below.
 * The same logo with a white background appeared on the first Burnout game.
 * Need for Speed 2 has the same logo, but it moves into the screen with engine sounds, and the floor has several lighted circles it passes by.

Technique: None.

Music/Sounds: The closing/opening theme of a movie or show.

Availability: Common. The opening variant appears on various television shows that use the sound format, such as Series 5 of Thomas & Friends, episodes of The Simpsons on FOX, and the British series Stars in their Eyes on ITV from the time period as well.
 * Appeared in games, too (for example, the still version was seen on Krazy Ivan).

2nd Trailer (The Best Sound All Round! variant) (1989)
Logo: We start in a room with a sleeping cat and a goldfish. Then some guy crashes in the front door carrying a box with the "DOLBY SURROUND" logo on it. The camera zooms into the "DD" on the box and out of the "DD" button on his remote, which he then presses, resulting in sound waves striking toward his speakers around him. His room turns into a movie theater to the guy and cat's surprise, but the former starts watching the film and eating popcorn and the latter just looks on disinterested. The theater then turns into a stormy sea, as the cat is pulled underwater and the guy is being thrown around, eventually being briefly pulled in. He then presses the remote, turning the sea into a rock concert where he dances to the music as the cat jumps around. The guy presses the remote again, sending the two (the cat in an astronaut suit) to outer space, where a laser-shooting spaceship floats over them. Finally, the guy switches to a blank background, where he and the cat suddenly fall out of the shot. The "DOLBY SURROUND" logo appears with the text "The Best Sound All Round!" in drawn text that shakes. The cat walks from the right to the left with a sack. "Produced by Capstone Films and Wibbly Wobbly Films" (the animation companies) appears below.

Technique: The jiggly cartoon animation, produced by the aforementioned companies.

Music/Sounds: A calm, weird synth cartoon ditty plays throughout which turns into rousing orchestral music, a rock version of the ditty, which resumes near the end. Strange synth or cartoon sounds correspond to the animation. These sounds are placed on certain sides or pan around to demonstrate surround sound.

Availability: Unknown, possibly extinct. It can be seen on the aforementioned Dolby Consumer Guide to Home Theater VHS and possibly other promotional/demo releases.

3rd Trailer (1991-2001 [2005 in Germany])
Logo: We see "DD" doors closed on the whole screen, as they open wide and "SURROUND" floats by, then returns in opposite direction through the doors' holes. After this, "DOLBY" flies through the same door holes and the two words meet in distance. The doors close and move to the left, while the name is taken inside the rectangle. "PRESENTED IN" appears above (in different languages, depending on the country).

Variants:
 * A shortened version exists where the "DD" doors open right to when the "DOLBY" and "SURROUND" words meet in distance.
 * The "PRESENTED IN" text was also altered on some releases.
 * A German variant was also created.

Technique: The "DD" doors opening and moving, the floating text and the rectangle zooming in.

Music/Sounds: A quiet synth drone and bell toll to start, and a quiet 4-note string-section and synth jingle. Whooshing sounds are heard as the words and the rectangle fly around. The jingle ends with the synth chimes before fades out to silence.

Music/Sounds Variant: On the shortened version, after the quiet synth drone and bell toll, the string-section and synth jingle are shortened to 2 notes before the synth chimes come in earlier.

Availability: Rare.
 * It appears at the beginning of Spunky's First Christmas, Spunky's Circus Adventure and Spunky's Camping Adventure. It also appears on foreign VHS tapes in the UK and France, as well as the game Armored Fist 2.
 * Some Psygnosis Playstation games contain this logo, like G-Police.
 * The shortened version can be seen at the beginning of the Dolby Consumer Guide to Home Theater VHS from 1991.
 * It has also appeared for a short time in a Chuck E Cheese's in Dallas, Texas from 1996-1997.
 * Strangely, VHS tapes in Germany would continue to use this logo until 2005.
 * This can also be seen on various PAL laserdisc releases from Pioneer Entertainment.

4th Trailer (CANAL+ Poland variant) (1999-2004)
Logo: On a black background, we see a yellow flash with a lens-flare like effect along with the Dolby logo zooming out. Then as the Dolby logo stops, the flare moves to the "DD" symbol and quickly goes out. As that happens, we see that the "DOLBY SURROUND" logo is being wiped in with a white shimmer. Then, the logo fades out.

Technique: The lens flare, the logo zooming in towards us, and the wiping with shimmer.

Music/Sounds: The last part of the music from the City trailer.

Availability: Rare. Has been used on CANAL+ Poland to indicate a Dolby film.

5th Trailer (Wizard) (2002-2009)
Logo: In a hallway, we see a wizard standing in front of a giant hole in the floor. A clod and a wave of white particles comes out of it, with the wave sweeping across the floor as the "DOLBY SURROUND" logo in zooms into the camera and the cloud pushing particles into the air.

Technique: CGI.

Music/Sounds: Whooshes and hums.

Availability: Unknown. Available on the Dolby Demo Disc "Explore Our World: We've Got the Whole World Listening".
