An ideal example of a vertically integrated firm will be:

a. Kinko's, which has a photocopy store near many colleges and universities

b. Sylvania, which produces light bulbs, notebooks, camcorders, and so on

c. Hertz Car Rentals, which has offices that help people rent a car in one city and drop it off in another city

d. American Apparel, which controls the dyeing, finishing, designing, sewing, cutting, marketing and distribution of its product from a single building in downtown LA

e. Intel, which makes computer chips for most of the computer manufacturers
