I've been trying to come up with a more accurate percentage of the Fortune 500 companies that are currently using an AS/400, iSeries, i5, or IBM i system in the U.S. Usually people quote 95% as the number of companies doing so but that seems pretty unrealistic.
I've divided the companies into two spreadsheets, one which shows the companies that are either using the system now or who have used it in the past.
There are 240 companies on the spreadsheet showing companies who are, or who have, used the system and I've confirmed that at least 158 of them are still using it. That leaves another 82 that I'm in the process of tracking down.
The other spreadsheet is the one I'd like some help with if anyone has the time. It lists the 260 companies who have never used any iteration of the system as far as I can see. If some volunteers could download this spreadsheet, which is attached, highlight the companies they know something about, and tell me if they're on or off of the platform, and then send it to me at email@example.com I'll go ahead and add that info to the Company List that's due to be posted on the all400s.com web site at the end of April. Since anyone can download this Company List for free you'll be helping a lot of people by doing this.
