The Cartoon Network Logo is one that most 90's kids will recognize without a problem.  The network and logo were introduced in 1992.  The current logo is pictured in the far left corner and was created by an Australian digital visual effects company called Animal Logic.  The font is a custom typeface that is San Serif.  The logo is very recognizable but I'm not sure how I feel about the original logo.  Each letter of the title is in a box and the entire logo has a stroke around it.  The font is a bold san serif font that stands out and makes an impression on the viewer.
