Understanding The Meaning of "Exclusive"

Unlike David Brody, I am not a journalist and don't regularly get asked to host programs and provide insight on CNN ... so maybe there is some journalistic definition of the word "exclusive" with which I am unfamiliar:

EXCLUSIVE: Video of Pastors Physically Blessing Obama's Inaugural Walkway
January 9, 2009

You have to check out this video. It was sent exclusively to The Brody File.

The video in question is of Congressman Paul Broun, Rob Schenck of Faith and Action and Patrick Mahoney of the Christian Defense Coalition anointing the doorway President-Elect Barack Obama will pass through on his way to being sworn in next week ... which we posted last week:

Considering that Schenck and company sent out a press release about it on January 7th and then posted the video the same day on Schenck's Faith and Action YouTube page, at which point we and others wrote about it, it's hard to understand how this is in any way a Brody File "exclusive."
