Crossing the chasm

In a course I teach, Requirements Management with Use Cases, one of the sheets mentions something about crossing the chasm. I always had some trouble explaining the expression to my (Dutch) students, but fortunately I stumbled an article on the subject that referenced a book called “Crossing the Chasm”.
In that book, Author Geoffrey Moore makes the case that high-tech products require marketing strategies that differ from those in other industries. His chasm theory describes how high-tech products initially sell well, mainly to a technically literate customer base, but then hit a lull as marketing professionals try to cross the chasm to mainstream buyers. This pattern, says Moore, is unique to the high-tech industry.
