Logo (2007-2015?)
Visuals: Over a white-gray background is the 2007 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.
Audio: 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.
