TVO Productions
From the Audiovisual Identity Database, the motion graphics museum
(2006?-2015?)
Logo: On a white-gray background, we see the 2006 variant of the 1992 TVOntario logo, which is an American Typewriter-ish font spelling out "tvo" in white, inside a red-maroon round-edged rectangle. Below it is "makes you think", in black.
Variant: More often than not, the logo will be seen in-credit, with or without the slogan.
Technique: None.
Music/Sounds: The closing theme to the show.
Availability: The actual on-screen variant is seen only on the first 2 seasons of Martha Speaks. The in-credit variant is more common, but not by much.
