There is the story of a man who killed the goose that laid golden eggs. Similar is the case with BCCI.
Recent ODI series in India against England witnessed large number of empty seats in Hyderabad, Delhi, Mohali, Bombay and Calcutta. There was drop in television viewing. The law of diminishing returns was at work. Within six months of World Cup interest in cricket had declined. During World Cup there were long queues for tickets for matches played by India and in some cases there was lathi charge. For the past four years there have been Tests, ODIs and T20s one after the other and people were bound to lose interest at some point.
When IPL began it provided an alternative to people fed up with K serials. Soon K serials disappeared. In 2009 and 2010 T20 World Cup was after IPL. In 2011 IPL was after ODI World Cup which India won and there was less interest in IPL.
Many cities host at least one Test or ODI every year. In those cities people have spent enough money and seen enough cricket. At one time when Tests were few and there was no TV in most parts of India every stadium used to be full for every Test. Then came ODIs, more Tests and spread of TV. Crowds for Tests in stadia declined. ODIs had full crowds. Then ODIs featuring India had full crowds and other ODIs had less spectators, sometimes very few in a stadium. Now even ODIs featuring India do not have full crowds.
Many Indians watch football and car race and interest in cricket is likely to decline. With less people watching there will be less money and that means decline of BCCI’s clout. That may mean politicians and businessmen leaving BCCI and cricketers running BCCI.
