Witt/Thomas Productions

Background
Witt/Thomas Productions was a production company that was formed in 1973 when Paul Junger Witt joined with Tony Thomas, the son of comedian Danny Thomas. In 1976, the company was renamed to Witt/Thomas/Harris Productions when writer and Witt's wife, Susan Harris joined the company with their first series Soap a year later. In the 1980s, the company was renamed back to "Witt/Thomas Productions", but the Witt/Thomas/Harris name continued until 1995 when Empty Nest ended.

Logo (September 4, 1975-April 27, 1999)
Visuals: On the closing credits, we see this text, often in a Clarendon Bold font on most shows produced by the company:

A WITT THOMAS HARRIS PRODUCTION

Variants:
 * During the later years, it was referred to as "A WITT/THOMAS PRODUCTION", although this variant of the logo was 1st seen on It's a Living as well as the ABC sitcom Condo from early 1983, which was seen with a copyright notice.
 * Beginning in 1994, the "Witt/Thomas" ("Witt-Thomas-Harris" for Empty Nest) in-credit name was shown outside of the credits and placed on a black background with a gradient shade of blue to make it seem like an outside logo. The font changes depending on the show.
 * On the 5th and final season of Blossom, the logo was placed on a black background.
 * On the pilot episode of Herman's Head, the company name is written with the names in separate lines, but without Harris.
 * On Beauty and the Beast, the two names are separated by a hyphen instead of a forward slash and superimposed into the credits.
 * On the series Woops!, the company name is placed in a dark blue background, and the two names are separated by a hyphen.
 * On some episodes of Herman's Head, the variant above is seen, but it's shown in-credit.
 * During the 3rd and final season of Nurses, this logo was in a double-font combo, much like the closing credits from that season.
 * During the later years of Benson, as well as Hail to the Chief and the 1985-89, 1st-run syndicated episodes of It's a Living, the copyright notice is in the Helvetica font.
 * On the Blossom episode "Rockumentary", instead of the usual in-credit logo, the logo is in a pink color at the bottom of the screen on a black background with a live action shot of Dreyfuss the dog from Empty Nest inside a circle (which is also in a pink outline) with the barking being dubbed by Blossom (Mayim Bialik).
