During the 1970s, the Japanese film market shrank due to competition from television. This reduced Toei animation's staff and many animators went to studios such as A Pro and Telecom animation. Mushi Production went bankrupt (though the studio was revived 4 years later), its former employees founding studios such as Madhouse and Sunrise. Many young animators were thrust into the position of director, and the injection of young talent allowed for a wide variety of experimentation. One of the earliest successful television productions in the early 1970s was "Tomorrow's Joe" (1970), a boxing anime which has become iconic in Japan. 1971 saw the first installment of the "Lupin III" anime. Contrary to the franchise's current popularity, the first series ran for 23 episodes before being cancelled. The second series (starting in 1977) saw considerably more success, spanning 155 episodes over three years.
