Henson Associates, Inc.

Background
Henson Associates, Inc. was formed on November 20, 1958 as "Muppets, Inc." by Jim Henson and his wife Jane, three years after Henson's first show, Sam and Friends, premiered. Until the premiere of Sesame Street in 1969, the company mainly did work for commercials. In 1976, Muppets, Inc. was renamed Henson Associates, Inc., and it became Jim Henson Productions in 1987.

1st Logo (September 15-December 8, 1984)
Visuals: Over a solid beige background, there is "Times New Roman", with "HENSON ASSOCIATES, INC." in an ITC Avant Garde font below it, and "For" placed on the top left of it, arranged like this: For Times New Roman HENSON ASSOCIATES, INC.
 * The exclamation point shines from top to bottom.

Trivia:
 * The logo was designed by David Kaestle and debuted as a print logo in 1975. When the company introduced new stationery that year, the logo was printed twice on the back of the paper so that, when it was folded, the recipient would be greeted with "Times New Roman". The design would also be adapted for other company divisions, including "Times New Roman" (Henson Enterprises), "Times New Roman" (Henson Electronic Products), "Times New Roman" (Henson International), "Times New Roman" (Henson International Television (later HiT Entertainment)), "Times New Roman" (The Henson Organization, Ltd.), "Times New Roman" (Henson Organization Publishing), and "Times New Roman" (Henson Universal Music).
 * The "Times New Roman" logo is still in use today as the print logo for Henson Alternative.

Technique: Scanimate.

Audio: The closing theme of the show.

Availability: It appeared on Season 1 of Muppet Babies. Reairings of the show plastered the logo with newer Henson logos (eg, Jim Henson Productions/Jim Henson Television). It was last seen when the show was rebroadcast on Playhouse Disney Australia in the Mid-2000's.

2nd Logo (September 14, 1985-January 21, 1986)
Visuals: Transitioning from the Marvel Productions logo, the "Times New Roman" from the previous logo fades in and zooms out, and when it stops zooming, the background changes from blue to a beige gradient. "HENSON ASSOCIATES, INC." appears stacked below it, arranged like this: Times New Roman HENSON ASSOCIATES, INC.
 * Again, a copyright notice appears below.

Variants:
 * An early version exists that had the word "For" next to "Times New Roman" (like the first logo).
 * The Muppets: A Celebration of 30 Years utilizes a cut-short version of this variant (as to avoid showing the Marvel Productions logo), likely because they lacked another logo to use.

Technique: Scanimate.

Audio: Same as before. On The Muppets: A Celebration of 30 Years, Zoot blows his saxophone.

Availability:
 * It appeared on Season 2 of Muppet Babies. Like the first logo, it was also plastered with newer Henson logos (eg, Jim Henson Productions/Jim Henson Television) during many reruns.
 * Also, this is usually preserved on the 1986 special The Muppets: A Celebration of 30 Years.

3rd Logo (September 13-December 27, 1986)
Visuals: Over a white background, there is: HENSON ASSOCIATES, INC. with a copyright stamp below in black. The text bears a strong resemblance to the zooming variant of the previous logo.

Technique: A printed card.

Audio: Plays over the ending theme.

Availability: Only appeared on season 3 of Muppet Babies.
