When microwaves were new, they often cost over $300, were huge, and had numerous settings and options. brenda and bart waited, concerned about potential health hazards and wishing for more choices in the market. by the time they purchased a microwave, sales of microwaves had leveled off and prices had declined significantly. brenda and bart were part of the diffusion of innovation group.

late majority

Explanation:

                In the society, innovations or new technologies are not adopted by everybody at the same time. However the innovations are adopted at different times by different peoples. The adaptation is a time sequence and it can be categorized into adapters classification depending on how long the the adapters took to  adapt or start using the new innovation.

               The late majority of the diffusion of innovation group includes the 34% of social population.  They adapt the new innovation just after a average person begins the adaptations. For them, adaption is a result of economic necessity and not because of motivations.

               Here Brenda and Bart purchased a microwave, when the sales of microwaves had leveled off and prices had declined significantly.

Thus they formed the late majority diffusion of innovation group.
