In 1977, Nelvana made its symbol. This symbol has a white polar bear with black colored edges.
A new logo was unveiled on September 14, 1985. They added more stuff to the 1977 Nelvana logo, including the wordmark in red text, and the 7 yellow stars encircling the polar bear, and the polar bear changed to blue. It was still used on old shows until 1995.
The logo was updated on December 2, 1995. All the red and yellow colored stuff changed to dark blue colored stuff, except the stars. The 7 stars are white and now are in a dark blue arc. This was used until 2004 along with the 1999 logo.
In 1999, Nelvana made an alternate logo which was used until 2005. Everything was the same, except the wordmark. The text is in a different font now.
A new logo was released on September 7, 2004. The polar bear was improved, the stars and the arc are removed, and the wordmark is in a bold font. This logo is still used in tandem with the logo below as a production logo.
In October 2016, the logo was changed yet again. The polar bear is more stylized, with the text in another font and lowercase letters.
