Borland International Inc cites Software Publishers Association figures to back a claim that its Quattro Pro spreadsheet is zooming up the popularity charts to account for 28% of the spreadsheets sold by number in the US and Canada in the first quarter of 1990 – but that did include ones sold under special introductory offers: the company says that Quattro Pro accounted for only 5% of spreadsheets sold in the second quarter of 1989, rising to 7% in the third, 16% in the fourth quarter; the company also quotes market researcher Techtel Corp, Emeryville, California that penetration in North America during the first quarter matched that of Lotus 1-2-3, 2.2, a milestone achieved by no other spreadsheet product against Lotus 1-2-3 in the five years we’ve been measuring the market; the aggregate installed base of 1-2-3 spreadsheets of course remains much larger than Quattro.
