Tournament basis is not at all beneficiary..
If Board signs a contract ex. of 1 billion per year for 5 years then they know atleast for 5 years they have assured the amount but Tournament basis will give no assurance. Ex. if PCB able to conduct Pakistan Vs. India in UAE we all know STAR SPORTS will bough the rights of ex. 2 billion then what next after that series ?? There is no assurity of the profit, it might double the figure or might not see the Broadcasting of the whole series means 0 money.
