Software Arts, founded by Dan Bricklin and Bob Frankston to develop VisiCalc, and VisiCorp, one of the earliest software publishers, settled their lawsuit over VisiCalc, the first "killer app" for computers, out of court. VisiCorp, which had taken over distributing and marketing VisiCalc, brought the sixty million dollar suit against Software Arts, alleging that the company had not maintained the software's competitive edge. Software Arts filed a suit in turn alleging that VisiCorp was not effectively marketing the product. Terms of the settlement were not disclosed to the public.
