News conferences are sometimes held by politicians (such as the President of the United States); by sports teams; by celebrities or film studios; by commercial organizations to promote products; by attorneyss to promote lawsuits; and by almost anyone who finds benefit in the free publicity afforded by media coverage.
A news conference is announced by mailing or faxing an advisory or news release to assignment editors, preferably well in advance. Normally they are held in hotel conference rooms or other formal settings; they may also take place at disaster sites, courthouses or other places where news is breaking.
In a news conference, one or more speakers may make a statement, which may be followed by questions from reporters. Sometimes only questioning occurs, sometimes there is a statement with no questions permitted.
A White House news conference is customarily ended by the senior White House correspondent (Helen Thomas) saying, "Thank you, Mr. President." President George W. Bush, who reportedly dislikes Thomas, declines to follow the tradition of allowing Thomas to end news conferences. Mr. Bush is known for having far fewer news conferences than other Presidents.
A media event at which no statements are made, and no questions allowed, is called a photo opportunity.\n
