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 (1983-January 21, 1986)
Visuals: There are two main variants of this logo: For Times New Roman HENSON ASSOCIATES, INC.
 * Version 1: On a solid background, we see "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:
 * The exclamation point shines from top to bottom.

Times New Roman HENSON ASSOCIATES, INC.
 * Version 2: Transitioning from the Marvel Productions logo, the "Times New Roman" from the above variant fades in and zooms out, and when it stops zooming, the background changes to a gradient. "HENSON ASSOCIATES, INC." appears stacked below it, arranged like this:
 * Again, a copyright notice appears below.

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.

Variants: The second main variant had a couple of minor variations:
 * An early version exists that had the word "For" next to "Times New Roman" (like the first version).
 * 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: Plays over the ending theme. On The Muppets: A Celebration of 30 Years, there is Zoot blowing his saxophone.

Availability:
 * It appeared on the first two seasons of Muppet Babies (with both variants being used), but it's usually replaced with a Jim Henson Productions/Jim Henson Television logo. It was however kept when Playhouse Disney UK reran the show in the mid-2000's.
 * The second variant of this logo is usually preserved on the 1986 special The Muppets: A Celebration of 30 Years.

2nd Logo (September 13-December 27, 1986)
Visuals: On a white background, we see: 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: None.

Audio: Plays over the ending theme.

Availability: Only appeared on season 3 of Muppet Babies.
