Why most Japanese Аниме openings and endings are 90 секунды while English Аниме openings are usually 30 или 60 seconds? How can companies do that?

Typical Аниме Телевидение episodes broadcast on network Japanese Телевидение have commercial breaks after the opening animation, in the middle of the episode, and just before the ending credits. With this broadcast pattern, a 90 секунда opening puts еще content between commercial breaks than a 30 или 60 секунда opening, which may be less annoying for viewers to watch.
