Under Daniel Carp, Fisher's successor as CEO, Kodak made its move in the digital camera market, with its EasyShare family of digital cameras. Kodak spent tremendous resources studying customer behavior, finding out that women in particular loved taking digital photos but were frustrated in moving them to their computers. This key unmet consumer need became a major opportunity. Once Kodak got its product development machine started, it released a wide range of products which made it easy to share photos via PCs. One of their key innovations was a printer dock, where consumers could insert their cameras into this compact device, press a button, and watch their photos roll out. By 2005, Kodak ranked No. 1 in the U.S. in digital camera sales that surged 40% to $5.7 billion.
