Like most innovations, Kiva is not entirely new. Rather, it is an ingenious fusion of older ideas. One is child sponsorship, which Save the Children pioneered in 1940. A family in a rich country sends $10 or $20 each month to a designated child in a poor country via a charity. In return, the family receives a photo and an update at least once a year. When I was perhaps eight, my family sponsored Constance, a Greek girl about my age, through Save the Children. I remember looking at her solemn face in two successive black and white portraits, trying to judge how much she had grown in a year.
