Brainstorming to me is a highly dynamic group interaction for problem solving. In other words it is a group creativity technique designed to generate a large number of ideas for the solution to a problem. The method was first popularized by Alex Faickney Osborn in the late 1930s, an advertising executive and one of the founders of BBDO (Batten, Barton, Durstine & Osborn), in a book called Applied Imagination. Osborn proposed that groups could double their creative output by using the method of brainstorming. Another use for brainstorming is a valuable team building exercise.
