Concurrence is a presentation program developed for NeXTSTEP by Lighthouse Design.
History[]
Development[]
Steve Jobs using Concurrence on an IBM ThinkPad running OpenStep at Macworld Expo.
Lighthouse co-founder Roger Rosner was the project leader and principal architect of Concurrence, though he left the company soon after it shipped.[1][2]
Release history[]
- Concurrence 1.0 (1992)[2]
- Concurrence 1.2
- Concurrence 2.0 (1994)
- Concurrence 2.5 — manifested an EPS linking bug in NeXTSTEP 3.3 which was fixed by a patch.[3]
- Concurrence 2.7
- Concurrence 2.77 (1997)[4]
Discontinuation and legacy[]
Lighthouse Design was acquired by Sun Microsystems and some of their software was ported to Java. Rosner was later hired by Apple Computer, where he directed the development of Keynote, which contained many user interface similarities. Though Sun CEO (and Lighthouse co-founder) Jonathan Schwartz was aware of this, he took no action until Apple CEO Steve Jobs called to complain about the resemblance of Project Looking Glass at Sun to Mac OS X at Apple. Schwartz then brought up Keynote's resemblance to Concurrence, which Jobs was known to have used. Despite the potential legal issues, neither took action against one another for this.[1][5][6]
