Digital cameras are now in about 43 mln homes in America, and that 40% penetration could reach 70% by 2007. In the United States, prints ordered from retailers and Web sites or made at home fell from a peak of 30.3 bln in 2000 to 27.4 bln in 2004 and could dip to 25.9 bln in 2005 according to Photo Marketing Association International. Propelled by price wars among retailers led by Wal-Mart, Costco, and online upstarts like Snapfish and Shutterfly.com, prints from digital cameras could hit 7.7 bln this year, up from 400 mln in 2000, and outnumber prints from film cameras by 2007.
