Marvel Productions

Background
In the late 1970s, DePatie-Freleng Enterprises had produced two shows for Marvel Comics, namely The New Fantastic Four and Spider-Woman. By 1980, co-founder Friz Freleng left the studio for the reopening of the animation department for Warner Bros. Marvel Comics Group bought out DFE on June 19, 1980, and it was renamed to Marvel Productions. Co-founder David H. DePatie continued working for the company as studio head, until his retirement in 1985.

In 1983, Marvel Productions joined forces with Sunbow Entertainment, who ended their venture in 1987.

In 1986, Cadence Industries was liquidated and sold Marvel Entertainment Group to New World Pictures, both of which later became part of New World Entertainment. Although MEG was later sold, New World kept hold of Marvel Productions, and in 1992, the studio became part of a new division of New World, called New World Family Filmworks. A year later, the studio was renamed as New World Animation.

1st Logo (February 14, 1981-1988)

Visuals:
 * Long version: On a blue background, several large sets of thin lines rotate in different directions. Over the lines, a "star" traces out a stylized "MP", with another "M" cut out of the "M" part of the logo. When the logo is fully traced and the lines are in position (with horizontal lines for the "M" part and vertical lines for the "P"), the logo flashes as all lines fade out, and the "M" cut out turns white while the rest turns yellow. After the logo shrinks to the top-left corner, the text "MARVEL PRODUCTIONS LTD." (in Bauhaus 93) is "wiped in" by a star. Another star forms the byline "A CADENCE COMPANY" in the same fashion below the logo.
 * Short version: On a blue background, white grids rapidly converge together to form the logo in blue at the top of the screen with the usual text forming below (the byline is closer to the company name this time). The "O" shines with a "ping".

Variants:
 * The Grinch Grinches the Cat in the Hat has a (.*) variant of the logo with a DePatie-Freleng byline. the logo's BG is much lighter than the normal logo.
 * Sunbow-Marvel Combo Variant: See Sunbow Entertainment for description. A bylineless version of the logo on this variant also exists.
 * On the cartoon series Meatballs and Spaghetti, the InterMedia logo is seen above the Marvel Productions logo. The Marvel logo has a shining light effect directly behind it.
 * Another cartoon series, Pandamonium, has the InterMedia logo below the Marvel Productions logo. The "MP" also shines the same way as in the Meatballs and Spaghetti variant.
 * In The Pink Panther in: Pink at First Sight, the logo lacks the "MP" altogether, and simply says "A MARVEL PRODUCTION" in the same font as the logo. On the bottom is a Mirisch-Geoffrey/DePatie-Freleng and United Artists byline. The normal logo's music is intact.
 * On the test pilot of the cartoon Defenders of the Earth, the still logo and byline are seen in white with "PRODUCED BY" above it.
 * On the Little People Video series of direct-to-video releases, the logo has a darker blue background, is still, and has the byline "A NEW WORLD COMPANY".
 * Still variants exist with the logo superimposed into the background. A mid-'80s airing of an episode of Spider-Man and His Amazing Friends had this with the Cadence byline in a white rectangle.
 * The short version was used in Margo the Mouse, though it uses same credits music as My Little Pony and its descendants.

Technique: Camera-controlled 2D animation.

Audio: A dramatic orchestral fanfare composed by Rob Walsh.

Audio Variant: The end theme of the show may finish over it, especially the short and still variants.

Availability:
 * Most Marvel shows of this time (The Incredible Hulk, Dungeons and Dragons, the 1981 solo Spider-Man series, Defenders of the Earth) have been updated with either a newer Marvel logo and/or the 1996 Saban logo.
 * However, you may still see this logo on some videos of Marvel shows of this time.
 * It also turned up when Spider-Man and His Amazing Friends was rerun on Toon Disney and Disney XD (the logo is still present on the Disney+ prints).
 * The still variant with the DFE byline is rare, and it was seen only on The Grinch Grinches the Cat in the Hat, the last Dr. Seuss/DFE animated special.
 * The short version also appeared on the failed Solarman pilot, made in 1986 but released on video in 1989, then aired only once on Fox Kids in 1992.
 * The still version with the New World byline only appears on the Little People Video series of direct-to-video releases, released in 1988 by New World Video, consisting of Favorite Songs, 3 Favorite Stories, A Visit to the Farm, Jokes Riddles and Rhymes, Christmas Fun, and Fun With Words.
 * The C&G Video/Starmaker Entertainment reissues keep this logo, as do international releases.
 * The version without the "MP" was only seen on the Pink Panther special Pink at First Sight.
 * The first episode of the 1981 solo Spider-Man series on Disney+ also retains this logo and the ARP Films logo (as it appears to have been transferred from an aged film print); the rest of that series plasters this logo with the next one. (and is taken from videotape masters).

2nd Logo (September 13, 1986-December 12, 1993)

Visuals: In space, the screen pans out through a series of orange glowing CGI bars. As the bars rotate up towards the camera, they are revealed to be part of the "MP" logo, done in glorious 3D (and with the "M" cut-out, not filled in). In the background, Spider-Man (also in CGI) flies up from below, and the logo is "absorbed" into his body, turning him silver. The space background turns into a "time warp mode" into a silver-black gradient background, as the words "MARVEL PRODUCTIONS LTD." rise up from the bottom-right with a trail behind them. The "MP" logo returns to the screen, as the silver Spider-Man somersaults to the top of it and takes a prowler-like stance above it as the logo takes its place on the center of the screen (Spider-Man's eyes return shortly after). The text takes its place below the logo.

Trivia:
 * The reason for the "MP" logo being absorbed and then mysteriously reappearing is to provide a place to cut the logo so that it is not as long. In most cases, however, the logo is shortened so that only the tail-end of the animation is seen.
 * This logo was designed and animated by Gary Demos and John Whitney at Digital Productions (known for The Last Starfighter, 2010: The Year We Make Contact, and Labyrinth).

Variants:
 * From 1987 to 1991, the byline "A NEW WORLD COMPANY" fades in below the logo.
 * A still variant exists.
 * On late '80s Henson co-produced shows, a copyright stamp for Jim Henson Productions fades in below.
 * Sunbow-Marvel Combo Variant: See Sunbow Entertainment for description.
 * On Robocop: The Animated Series, the logo fades into the 1988 New World International logo.

Technique: CGI, rendered on the Cray X-MP/48 supercomputer and a DEC VAX-11/780 mainframe. The modeling was done on an Evans and Sutherland PS-300 terminal. The animation was done on an IMI 500 display monitor. The texturing and lighting was done on a Ramtek 9460 framebuffer. The logo was recorded to 35mm film on a III PFR-80 (the company Gary and John worked at before they founded DP).

Audio: It begins with a THX-like "chord" sound with some futuristic "whooshes", then a synth note that plays deeper toward the end.

Audio variants:
 * At other times, the ending theme plays over it.
 * On the 1989 pilot Pryde of the X-Men, as well as later episodes of Robocop: The Animated Series, the music from the Metrolight Studios logo continues into this logo, as well as that of New World International.
 * The 1990 educational videos Spider-Man: Don't Hide Abuse and Spider-Man: What To Do About Drugs feature an extended version of the theme. Here, it begins with a "clang", followed by a "whoosh" as the "MP" is revealed. When the logo is "absorbed", a brief synthesized "whoosh" is heard. When the text appears, an ascending chime sounder is heard, before the theme culminates into the normal music (albeit with a shortened ending).

Availability:
 * The short version was seen on many shows, including the late 1980's Marvel Action Universe block (Dino Riders, RoboCop, and the Pryde of the X-Men pilot), the first season of Biker Mice from Mars (New World Animation took over from the second season onwards), the animated Blondie & Dagwood special (and its sequel, Second Wedding Workout), Rude Dog & The Dweebs, Spacecats, and the animated adaptation of Attack of the Killer Tomatoes.
 * It was most notably seen on Henson co-produced shows like Muppet Babies and Fraggle Rock (the animated version).
 * The long version was normally used to plaster the original logos on later prints of pre-1986 Marvel shows such as Spider-Woman, the 1978 cartoon The New Fantastic Four, the 1981 Spider-Man cartoon and even the 1966 series The Marvel Super Heroes; it also appeared on early '90s video releases of Marvel material.
 * It also plasters the previous logo on some later prints of Dungeons & Dragons (albeit on the Contender DVD releases of the series, the logo doesn't always appear) and also appears on RoboCop: The Animated Series (and remains intact on DVD releases, normally paired up with the 1988 New World International logo).
 * The extended music variant was found on Spider-Man: Don't Hide Abuse and Spider-Man: What To Do About Drugs, two in a series of four educational Spider-Man VHS tapes titled Spider-Man Safety Series that were distributed to schools, and since the remaining two remain lost, it is unknown if those videos have this variant as well.
