In the last edition of Fortune Analytics, two weeks ago, we looked back at how the Fortune 500 changed in 1995, integrating “service” companies (think banks, retailers, utilities) for the first time in a list that previously had featured only “industrial” corporations.
The growth in scope of the ranking means that today, it includes companies across 21 sectors, from Aerospace and Defense to Wholesalers. To drill down deeper and examine the biggest players in these sectors, Fortune today has introduced our first collection of Fortune Sector Leaders rankings.
