According to the Daily Beast, Disney have done a product test with teens and tweens and the Jonas Brothers are jumping the shark at the speed of something really really really fast.
Pre-tweens still like em, though the refurbished second season of the TV show, now called Jonas LA as a kiddies enyourage should scare em away. Tweens 9 – 10 year olds think they’re dweebs though they all know someone else who is obsessed with them. And 12 to 13 year olds could care less.
Apparently taylor Lautner has single handedly dethroned em.
If this season tanks, the Jonas Bros are in serious trouble. The first season tanked, the 3D concert movie tanked (that’s the move that cememented Miley’s stardom), the last album tanked, the solo album tanked and unless they are willing to do it all for love of music, like Hanson have, they are fucked.
