===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) was aware of this, he took no action until Apple CEO Steve Jobs called to complain about the resemblance of 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.Former Sun CEO Jonathan Schwartz describes Steve Jobs showdown by John BrownLee, Cult of Mac. 2010-03-10.HOW - TO: Steve Jobs Keynote with Concurrence by Mitch Green, NeXTWORLD.
