The sector that had done best was that of services, which grew at an average of 8.1 per cent a year through the 1990s. Much of this was contributed by the software industry, whose revenues grew from a paltry $197 million in 1990 to $8,000 million in 2000. In some years the industry grew at more than 50 per cent a year. Much of this expansion was aimed at the overseas market.
