There are undeniable benefits to having bands split the way they so frequently do. The original band continues with the same level of success, and the new band gets an extreme jumpstart thanks to name recognition/association with the original band. In the end the label doubles their returns since the new band usually achieves a similar level of popularity.
I'm thinking of situations like the 50 Cent/Floyd Mayweather twitter stuff, Drake/Common feud, Lil Wayne/Pusha T, things like that where there's no real animosity between the people involved and they're just doing it to generate attention for both artists.
Wouldn't they have the same level of success just by saying that the member split because of creative differences or something along those lines?
I'm pretty sure the only one of those that was actually fake was the 50 one, the other ones perhaps were blown out of proportion, but they were there. I could be wrong though, I don't really pay attention to that stuff.
