Dealerscope researched 70 large consumer electronics retailers to devise its registry of the Top 50.
Information on total sales, store counts, etc. was gleaned from readily available sources, such as SEC filings, Hoovers listings, Forbes listings, corporate press releases, corporate homepages and electronic databases. Estimates of consumer electronics sales were gleaned from SEC reports and from information previously published in the mainstream and trade press.
Dealerscope telephoned each retailer listed in the registry no fewer than three times, giving each ample opportunity to confirm or contest the magazine's initial figures. Most took part in the survey, and many confirmed our consumer-electronics sales estimates. However, some private companies flatly refused to disclose sales information. Other companies, both public and private, could not or would not separate consumer electronics sales from their overall merchandise mixes. Finally, some companies simply did not return telephone calls. In these cases, Dealerscope chose to publish its best estimates.
