The British monarchy is a very valuable brand. A study by the company Brand Finance estimated its worth at about $70bn (£45bn).
The firm estimates that the newborn prince, the son of the Duke and Duchess of Cambridge, will add another $10bn to the monarchy's value.
The BBC's Sharanjit Leyl spoke to Samir Dixit from Brand Finance to find out how he arrived at such an eye-popping figure.
