System/360 (if you can count it as an app) was supposed to be $5 billion in the 1960's. So $34B + in todays dollars. http://www.wired.com/science/discoveries/

(And if you include the cost of further development of z/OS over the years that goes much much higher again)
- rhizome 14y agoI wouldn't be surprised if that was one of the priciest projects with the best ROI, though.
- whatusername 14y agoActually, thinking in terms of largest total return for a project (ROI is infinite if your I is 0).. I can't think of too many projects that have had larger returns. Probably the iPhone? Maybe some Cars (camry? Model T?) Maybe some really big mining/oil operations? What else is in the same league?
- rhizome 14y agoTo be sure, there has been marginal investment over the years in maintaining absolute backward compatibility through the zSeries/zOS.
