The influence of the mass media on American history has been overwhelming. "History of the Mass Media in the United States" examines the ways in which the media both affects, and is affected by, U.S. society. From 1690, when the first American newspaper was founded, to 1995, this encyclopedia covers more than 300 years of mass media history.
"History of Mass Media in the United States" contains more than 475 alphabetically arranged entries covering subjects ranging from key areas of newspaper history to broader topics such as media coverage of wars, major conflicts over press freedom, court cases and legislation, and the concerns and representation of ethnic and special interest groups. The editor and the 200 scholarly contributors to this work have taken particular care to examine the technological, legal, legislative, economic, and political developments that have affected the American media.

The governmental pledge to the American people is found in the First Amendment: "Congress shall make no law...abridging the freedom of speech, or of the press". Written more than two hundred years ago, these words now protect a wide range of expressive activity. Revolutionary Sparks is a broadgauged discussion of freedom of expression in America that begins by studying the period after the Civil War and Reconstruction when new and unsettling ideas appeared with great regularity on the American scene. These ideas were so widespread during this period that the nation's leaders often joined forces to repress aberrant notions. In response to such suppression, individuals seeking to better their lives through the expression of new ideas began to demand their rights to speak, write, and associate together to advance their points of view. With a broad grounding in political and social history, rather than the more prevalent legalistic orientation, Blanchard traces this contest for control through the Watergate scandal of the 1970s and the Reagan and early Bush administrations. Presenting the first comprehensive history of freedom of speech, Blanchard ranges from questions of national security to those of public morality, from loyalty during times of national stress to the right to preach on a public street corner. Including examinations of controversies involving the press, the national government, the Supreme Court, and civil liberties and civil rights concerns, Revolutionary Sparks presents a strong case for the right of Americans to speak their minds and to have access to the knowledge necessary for informed self-government.
