By monopoly, I didn't mean a family or two controlling the market. I was referring to a single conglomerate becoming too powerful. Of course, hardly any company can maintain absolute control over any sector of the market unless you are in Hong Kong. Tata Group and Reliance Industries Limited will do their best to prevent any other Indian conglomerate from becoming powerful enough to challenge the status quo set by them.But these powerhouses are not owned by a single family. Majority of their shares are listed on the stock market and are highly spread out amongst institutions and individuals. To create a monopoly is a publicly traded company with most diverse board members is extremely difficult and risky, simply because the same board members might have interest in competing businesses.
