Why is Shah Rukh Khan buying his own films?

Shah Rukh Khan is acting in his own production these days. But he acted in about 40 movies before starting to do movies under his banner. And now the actor is in the process of buying out the 40 movies. He already purchased the rights of the television series Idiot (1982) and the feature film Chaahat (1996), in which he played the lead role.

He is already in talks with the producers and is in the process of acquiring them. He is offering fancy prices to some of the movies so that the producers could not resist. While every one in Bollywood are surprised why Shah Rukh Khan is doing all this now after these many years, some people are saying that SRK wants to make a registered trade mark of his name and brand so that he can sell any content related to him or his movies at a higher rate.
