Well each network has its stronghold or weakness, sony cannot match star or zee in some segments or genres bcoz those r either saturated or held tightly by key players. Sony can try to invest heavily to make way thru certain genres but i think they would not risk it so high unless completely assured of returns.
Carrying this forward WB, Fox Life, And Flix, Zee Cafe might soon exit or revamp bcoz they r in even tougher spot than Sony Mix or others
