Kodak has a long history of firsts dating back to 1892, including the first-ever commercial DSLR, released in 1991. Two years before the Eye-Fi SD card made wireless photo-sharing as simple as could be, Kodak's EasyShare One became the first digital camera with built-in wi-fi capabilities. You could upload photos only to Kodak's EasyShare gallery — but no other camera manufacturer has been able to go even that far.
