ELI5: Explain Like I'm 5

Videotelephony

Videotelephony is a new kind of technology that lets you have a conversation with someone using a video camera. It’s like a regular telephone conversation, but instead of talking on the phone, you use a video camera and computer to see what the other person is saying. You can talk to a family member who lives far away, or have a business meeting with someone in another country - all without leaving your home.
