Marcus Bullock: An App That Helps Incarcerated People Stay Connected to Family

'Over his eight-year prison sentence, Marcus Bullock was sustained by his mother's love -- and by the daily letters and photos she sent of life on the outside. Years later, as an entrepreneur, Bullock asked himself: How can I make it easier for all families to stay connected during incarceration? Enter FlikShop : an app he developed that lets families send quick postcards to loved ones in prison and help keep open a critical line of support.' -- TED
