By some logic that means Bleach, Beelzebub, Reborn, Nurarihyon (for not being continued) are some sort of failures, as their anime were cancelled. Rookies didn’t receive anime, guess it’s a failure too. Aside from that most Jump series haven’t received anime, guess that means Jump's business it to produce failures? And in "half" the occasions of those that receive an anime, it gets cancelled XD
One series simply don’t run for 3 years in Jump, to end up being called failure by some “all-knowing” internet "experts". If it’s a failure, Jump cancels it quick, it doesn’t wait 3 years. Obviously it wasn’t a failure (receiving anime is no merit for being failure or not) as it was beneficial for them to leave it for 3 years. It doesn’t need to be their top series either to be beneficial.
And for those who say if people aren’t voting for it, it’s a bad/failure. How many people vote? You don’t know… You used Bakuman, if I remember correctly in Bakuman the first place was something between 500-800 votes (overall less than 10k voters)? Hell lots of series character popular poll get like 5-15k votes at best. How many people buy Psyren? More than those numbers. How many copies Jump prints and sell? 2.8 million or something? Most people are not only not voting for Psyren, they aren’t voting at all. And since they are also limited to vote for 3 series, if it’s your 4th or 5th favourite series, then you obviously can’t vote for it, unless you decide to not vote for another.
