This has given Weekly Shonen Jump a reputation of only allowing the best manga to be published, but at the same time, it’s also forced countless manga with potential to either end before they could properly develop or to ruin whatever worked for them in an attempt to boost their fledgling ratings.
Weekly Shonen Jump is infamous for having a very cutthroat business practice where any series that spends too long at the bottom of the popularity rankings is almost guaranteed to be canceled in due time. Not every Weekly Shonen Jumpmanga gets to become a hit, and some great manga get unfortunately canceled too soon, disappearing from Shueisha's premiere magazine.
