QM Productions

Background
QM Productions was an independent television production company formed in 1960 by Quinn Martin. All of his series were known for their highly stylized format: a prologue featuring a stern-voice narrator to establish the premise; explicitly announced Acts I, II, III, and IV; and an epilogue, again featuring the narrator. In 1979, a group of investors acquired QM and subsequently sold it to Taft Broadcasting Co., causing QM Productions to cease in 1983. Currently, most of the QM library is held by Paramount Global through CBS Media Ventures and Spelling Television Inc. with the exceptions of The F.B.I. and Banyon, which are currently owned by Warner Bros. Discovery via Warner Bros. Television, and 12 O'Clock High, which is currently owned by The Walt Disney Company via 20th Television.

2nd Logo (September 20, 1979-October 8, 1983)

Said object flies up towards the screen and a blue, stylized, and connected "QM" in 3D, with the word "PRODUCTIONS" the Taft byline below it, zooms out from the bottom of the screen to the center. After this, the logo shines.
