Compaq Computer Corp just squeezed past IBM Corp to take second place in personal computer market share in France in 1993, with 13.7% compared with 13.6%, after Apple Computer Inc, which has 14.7%, according to International Data Corp figures. The market saw volume growth of 9%, but it declined by 1.2% in value as prices fell between 22% and 28%. Compaq has not passed IBM elsewhere in Europe, although the gap is closing; Apple remains the leader in France by units. Says IDC analyst Eric Osch: [Apple] benefits from a very price-elastic demand for its products. The moment they drop, Apple’s volumes grow. Zenith Data Systems moved into fourth with 7.3% of the market, while Hewlett-Packard Co saw its volume share rise to 6.2% from 3.7% in 1992.
