Why isn't the national version of the basketball flying man (slam dunk) animated?

The National Basketball Slam Dunk was once planned to be animated, but due to various reasons, it could not be realized. The specific reasons were as follows: 1. Investment problem: animation required a lot of investment. At that time, the publication of comics was already quite successful, so animation needed a bigger investment. At that time, the animation industry was not very mature, so the cost of animation could be very high, making it impossible. 2. Time: The animation required time to complete the production, dubbing, and soundtracks. At that time, there might not be enough time for animation because the comic had been published for some time. Animation might have to wait for the comic's publishing company and other companies to complete their work. 3. The issue of copyright: The animation requires the copyright of the comic, which may require payment of copyright fees. At that time, the copyright of Slam Dunk was already quite expensive and might not be able to afford the cost of animation. Therefore, the national version of the basketball player (Slam Dunk) was not animated but continued to be presented in the form of a comic. Although he missed the opportunity to make an animation, the cartoon of Slam Dunk was still very popular and became a classic basketball comic.
