Transformers is (arguably) the most successful cartoon ever with a continuously popular TV show and toy line for over 15 years. Transformers first aired and released its initial toy line in 1984. The original Transformer series lasted a whole three seasons and a few season four episodes as well as a full length feature film in 1985 before it came to an end in 1987. In 1996, Transformers came back in their freshest incarnation show - Beast Wars! Beast Wars experimented with a new idea of transforming animals rather than vehicles with a more dynamic CGI 3D animated show. Many die-hard Generation 1 fans originally scoffed at the new idea, but Transformers winning formula eventually succeeded in converting old fans with the new show sporting numerous Generation 1 references. Beast Wars lasted three seasons until it ended in 1999 with the toy line still going strong today.
