The 1999 TWICE Personal Computer Retail Registry ranks the top U.S. retailers of computers by their estimated computer-related sales - including hardware, software, peripherals and accessories.

To be considered for the Registry, companies must have a substantial computer presence at retail. Where possible, corporate, government and education sales are excluded. Sales figures do include SOHO and small business sales. Retailers that are rental/purchase companies have been excluded.

Sales for the following are based on the approximate sales going to home users: CDW Computer Centers, Cyberian Outpost, Insight Enterprises, Office Depot, PC Club, Staples, Micro Warehouse and Multiple Zones. Sales for Micro Warehouse and Multiple Zones are also for their domestic operations only.

Sales for The Wiz are from the date of its acquisition by Cablevision Systems (February 9, 1998) through the end of the year and are not comparable with prior year figures. Figures for Future Shop have been converted from Canadian dollars at the rate of C$1=U.S.$.65 and are for U.S. stores only.

All sales figures, except for publicly held companies that break out line-of-business information for personal computer products, are TWICE research estimates, based on information from the companies responding to a TWICE questionnaire, public filings with the SEC, and discussions with industry analysts and suppliers. Additional information was gathered from published reports on the retailers and newspapers in the retail areas they serve.

Figures are given for the 12-month period ending closest to December 31. When warranted, past Registry figures for 1997 were revised and comparisons were made with revised figures. For purposes of comparison, sales were assumed to be flat for companies for which 1997 sales figures were either unavailable or not comparable.

Rankings were made by market research director Kay Anderson and research specialists Janice Chamberlain, Judi Fulbright and Diane Hoth, with help from research associates Cynthia Myers and Lisa Souther.

The Registry was compiled under the editorial direction of editor Steve Smith, senior editor Doug Olenick, managing editor John Laposky and copy chief Catherine Rutgers.
