Dan Curtis Productions

Background
Dan Curtis Productions was the production company of Dan Curtis, which was founded in June 1966. The company mainly released content based on Horror and Mystery for the big three networks during this period (ABC, NBC, CBS).

They were most known for Dark Shadows (including it's short-lived remake of the same name), and various TV movies, including The Norliss Tapes and their final production, Our Fathers.

(June 27, 1966-November 5, 1973)
Logo: Scrolling up in the credits of Dark Shadows, we see a superimposed logo with cursive-like text (the first letters of each word are in boxes) as follows:

Dan Curtis Productions, inc. copyright © (year) ALL RIGHTS RESERVED

Variants:
 * There was different variants of the logo seen on Dark Shadows where the background would be different (like in Episode 1082). In 1970-1971, it would be in color.
 * On some 1970-71 episodes, a text-only version was used as follows: DAN CURTIS PRODUCTIONS, INC. copyright © [year]
 * Another variation, seen on the 1969 TV movie Dead of Night: A Darkness at Blaisedon, is like the stylized-text version used on Dark Shadows, except the following copyright disclaimer is used: © MCMLXIX DONNYBROOK PRODUCTIONS, INC. All rights reserved It's also in a black background with lights shown.
 * On The Invasion of Carol Enders, the first letters are in a bold, normal font and the rest is set to a cursive font. It also has the copyright text: ⒸCopyright 1973

Technique: The text scrolling up in the credits.

Music/Sounds: The end theme of Dark Shadows, that can either be a spooky dark theme, and/or a deep voice-over with a echo/stutter-like effect saying, "Dark Shadows is a Dan Curtis Production."

Music/Sound Variant: In Dead of the Night: A Darkness at Blaisedon, it uses its own theme.

Availability: Found on all episodes of the original Dark Shadows TV series as well as The Invasion of Carol Enders. It also appears in the TV Movie Dead of the Night: A Darkness

Legacy: The theme and the announcer are notable for being ominous. But it is fitting due to the shows above are horror-related.
