How Many Companies Use Lotus Notes

In understanding the process of innovation and technology diffusion, it is important to analyze how long it takes for an outdated and unpopular technology to actually be eradicated from the market.

That is why I am interested in knowing how many companies use Lotus Notes there days.

I’m having difficulty finding credible information, but what I’ll find, I’ll post here.

From the salesforce.com blog;

Well, the reality is that Notes penetrated companies pretty darn well back in the 90’s (like a Nirvana song permeated the radio waves), and the departmental applications sprouted and filled all the holes that IT often couldn’t get to. Love it or hate it, Notes became a mainstay platform of the enterprise. In a recent survey we did of our Dreamforce 2012 attendees, we found that 73% did indeed still use Lotus Notes. And that 70.3% were considering replacing Lotus Notes, the majority within the year.

From an old source but which mentions that companies might not be using Lotus Notes for Email, but for other stuff, which would make a market share comparison rather difficult;

Jim goes on to explain, that by a wide definition of “use Lotus Notes and Domino software” even Microsoft would be a Notes customer.
