Since Skype started gaining popularity a few years ago, Josh says he's heard many stories that touch his heart. When one teenage girl got sick, he says she was able to finish 11th grade via Skype from her hospital bed.

This voice communication system may be part of his profession, but at home, he says he and his children use Skype for personal reasons.

"I picked up and moved my wife and children eight time zones away from their grandparents," Josh says. "I can't tell you what a meaningful impact it's had for my family. My kids still have a rich, real relationship with their grandparents where they get to see them and talk to them every week. Their grandparents can read them stories. My kids can show their art projects."
