For their support of the 1987 World Cup in Asia, the Associates were offered a new deal - a guaranteed £20,000 each as the World Cup share. This was against the £3000-4000 per member each Associate hoped to get if England retained the World Cup. Full Member nations were offered £75,000 each, plus expenses for participating in the event.
The total amount of the Prudential Assurance Company's sponsorship was £500,000, and the gate receipts came to £1,195,712. The aggregate attendance was 232,081, compared with 160,000 in 1975 and 132,000 in 1979. The surplus, distributed to full and associate members of the International Cricket Conference, was in excess of £1,000,000, this being over and above the prior payments of £53,900 to each of the seven full members and one of £30,200 to Zimbabwe.
In addition to the Trophy and silver-gilt medals for each player, India received £20,000 for their victory. As runners-up West Indies won £8,000. The losing semi-finalists, England and Pakistan, each won £4,000. There were also awards of £1,000 to the group winners, plus Man of the Match awards (£200 for the group matches, £400 for the semi-finals and £600 for the final).
There really wasn't too much surplus generated after the 1987 world cup as the rights were given to government broadcasters who even then wanted to get paid for broadcasting the matches instead of paying for the rights. The article on the 1987 world cup says it out clearly, India-Pakistan had to pay the associates an increased amount in order to get the votes needed for the world cup.
It was only at the time of hosting the 1996 world cup that TV rights came into play (with cable tv and private tv channels being popular) and that's when the Asian bloc really started monetizing the world cups. Australia probably monetized it the best in 92 though.
