I love video chats with my grandchildren and other family members. I also get invited to video chats for business meetings and occasionally also make video presentations to genealogy societies that may be hundreds or even thousands of miles away. A few years ago, I sat in the audience at a genealogy conference where the presenter was about 12,000 miles away but she appeared on a large screen in front of the audience. In fact, it was a two-way video conference: she could hear and see us as we watched and listened to her.
Video conferencing equipment used to cost thousands of dollars only a few years ago. The improvements in home computers since then has dropped the prices dramatically. Most of us can now participate in two-way video conferences at no additional charge by using the computers we already own.
