You might have heard that annoying "Ding ding ding ding dididing ding bing bing pscht" as a ringtone, but the history of the noise is longer. Bloggerheads digs into the Evolution of Crazy Frog and tracks where the sound appears in games, ads and online pranks.
Erik Wernquist (creator of the Crazy Frog character) and Daniel Malmedahl (endorsed by Erik as the originator of the sound file) appear to have agreed to the use of their intellectual property by the companies Jamba! and Zed, so we can assume that they have been compensated for any/all commercial use (but how fairly they have been compensated, I do not know).
