Yes, basically this: the big agencies that run the vast majority of the entertainment business have transformed from talent representation into "deal makers"... essentially producers who represent everyone involved in deal. In theory this streamlines the whole process. In practice is royally fucks everyone involved who is not already in a power position. Essentially now, if you are a writer or b-list celebrity, you almost need an agent to represent you when dealing with your agent.
