When the history of the early years of the personal computer industry come to be written, the extent to which Apple Computer Inc has captured the hearts and minds of the people in the graphic arts and media world is likely to be recognised as one of the biggest corporate breakthroughs: Apple people have done a great job in getting their computers seen in television plays about trendy businesses, and the Wall Street Journal, noting that desktop video production, merging graphics into videotape presentations by means of $1,500 boards that plug into a Mac, reports that Truevision Inc, whose Targa video-merge boards are currently designed for use in MS-DOS micros, is preparing a $4,250 board for the Mac because most video people want to use a Mac, all of which suggests that the battle is lost and won, and that Presentation Manager is much too late to have much market clout.
