The correct answer to this open question is the following.
After the Gulf War was over, 15 influential news organizations sent a letter to the secretary of defense complaining that the rules for reporting the war were designed more to control the news than to facilitate it. This situation affected the access to covering the next war in that media reporters were given greater access to cover combat and war affairs.
After the situation mentioned in the Gulf War, the Pentagon made an important decision that allowed reporters to better cover the incidents of the war. In 2003, almost 600 journalists closely followed the United State Army military actions in the war front, during the invasion of Iraq. The US government considered that better news coverage of the incidents in the war front would produce better support from their citizens. That kind of coverage facilitated the work of the reporters and the information shared by their agencies.
