No longer are proud parents just posting traditional baby pictures online to share with family and friends, but now ultrasound photographs are gaining in popularity. Social networking sites like MySpace are now filling up with 3D and 4D photos taken with advanced ultrasound machines. In an article on IslandPacket.com, one expectant mother said, "When you're pregnant, everyone's excited and wants to see pictures. Everyone's going to ask you to send it anyway." Demand for keepsake ultrasound photos has also caused an increase in demand for used ultrasound equipment, as entrepreneurs are setting up new businesses that cater to moms-to-be.
