Why Venkatesh Not Endorsing Brother's Business?

It is a common trend to see siblings helping each other in the film industry and sometimes few of them go out of their way to promote their brother or sister. But here is one man who doesn’t seem to be interested in doing such things and is busy in his own world. He is none other than victory Venkatesh.
 
The question that some of them are posing is, why doesn’t Venky take any interest in promoting the Ramanaidu Film School which has been started by Daggubati Suresh, his elder brother. As such, Venky is not a person who has got multiple projects to keep himself busy so why this indifference?
 
They are also quoting the example of Nagarjuna and how he is promoting his film institute in a big way. Those who know Venky closely say that he is more of a private person and doesn’t like to market himself or any of his businesses. For that matter, Venky doesn’t even take part in the promotion of his own movies then what he will do to his brother, is the argument.
