Are these shows all fake? I thought it was illegal to knowingly record someone’s voice without their consent? I am sure they get consent afterward, but don’t they legally need it before they record someone?
Depends on the state. Some states allow recording if either side agrees. So you produce the show in those states and you’re OK.
As further clarification: the laws only apply to phone calls. There are no laws requiring permission to videotape someone (otherwise, you’d have to get permission if a stranger is in the video of your trip to the beach). However, you cannot broadcast that video without permission.
