Thirty Mile Zone referring to the
30 mile radius around
Hollywood where all filming is considered local. Any filming outside of this zone is considered non local and entitles all involved in extra compensation.
TMZ is a syndicated celebrity gossip show, headed by Harvey Levin. They have paparazzi going all around the country, sometimes even underwater, to take photographs and interviews with celebrities and pseudo-celebrities.
The format of the show involves the staff talking about footage they have and usually injecting humor and other comments. They can be cruel at times but usually funny.
For such a voyeuristic enterprise, the people involved seem to have their privacy measures down pat. There is no easily available (read: googleable) information on their staff. No pictures, screen captures, names, bio, etcetera can be found about the people who work for TMZ. How they actually accomplished this is still beyond me.
