Any software that allows webcast conferencing?

[Drizzy]

My family is scattered all over the US and we rarely get a chance to get together. I was thinking it would be great if we could get a conference call software that would allow us to see each other every once in a while as a group instead of 1 on 1. I dont have thousands to spend on some software for business or something but was wondering if there exists any software that would allow this that wouldnt cost too much.. thanks!
