A is the ‘ideavirus’ curve. Ex: Myspace, Ideas that really take off like ‘The Long Tail’, ‘Big is the the new small’.
B is the ‘Flavor of the Month’ curve. Ex: Social Networks that are the buzz for 1.5 weeks.
C is the ‘Blogs’ curve. An idea that has tremendous potential but takes a few years to hit the mainstream and become a force.
D is the ‘Idea before its time’ curve. Ex: Thin Client PCs in the late 90s.
