After World War II, from 1947 to 1961, the birth rate sharply rose in America. This period was described as a baby boom, and those born during this time were baby boomers. Those born between 1961 and 1972, typically college educated but chronically pessimistic and vaguely dissatisfied with career possibilities, have been dubbed Generation X, a label drawn from a novel of that name by Douglas Coupland.

During the 1980s and 1990s, Americans heard a great deal about PACs. A PAC–Political Action Committee–is a special interest group, lobby, or pressure group organized to raise money for specific political activity.

“In God We Trust” is plain enough English. The Great Seal of the United States, reproduced on the dollar bill, also Includes two phrases of Latin: Annuit coeptis (“He has favored our undertakings) and Novus ordo seclorum (“A new order of the ages”).

Newt (Newton Leroy) Gingrich (b. 1943), elected U.S. Congressman from Georgia’s 6th District in 1979, became Speaker of the House in 1995. Intensely, abrasively partisan, the eloquent Gingrich brilliantly masterminded the Republican party’s so-called “Contact with America.” This conservative legislative agenda promised smaller government, more responsive government, and a renewal of a sense of opportunity in American life. Gingrich has drawn ardent admiration from conservatives and equally contempt from liberals.

In the 1980 presidential election, Libertarian candidate Ed Clark polled 920,8569 votes, but candidate David Bergland received only 227,949 votes in 1984. Ron Paul garnered 409,412 votes in 1988, and Andre Marrou received 281,508 votes in 1992.

The very last year of the 19th century saw the invention of radio—at the time called the “wireless telegraph”—by the Italian-Irish inventor Guglielmo Marconi (1874-1937). Twenty-one years later, Pittsburgh’s station KDKA made what is generally considered the first commercial radio broadcast in the United States (an announcement of election results), and electronic mass media was born. In 1933, a Russian-born American engineer for RCA, Vladimir Zworykin (1889-1982), having invented and patented in 1925 the “iconoscope” (basis of the modern “picture tube”), broadcast a television image over a radio-wave relay between New York and Philadelphia. It took well over a decade for the new medium to catch on with the American public, but in 1948, when an ex-vaudeville comic named Milton Berle (b. 1908) began cavorting across the small screen (often attired in drag), Americans got hooked. Berle’s Texaco Star Theater dominated the airwaves through 1956, sales of TV sets soared, more programming was developed, and television became the dominant American entertainment medium. Soon, it also displaced the newspaper as the dominant news medium as well.

Radio and television are essentially one-way media, broadcasting to a passively receptive audience. The development of the personal computer, especially as linked to other computers through such networks as the vast Internet, represents an emerging interactive medium, in which there may be many parties in an exchange of entertainment, news, and information.

The modern personal computer has its most direct origins in the “analytical engine” invented by Thomas Babbage and Lady Lovelace in 1822-37, in computational theory developed by the British mathematician Alan Turing in the 1930s, and in ENIAC, the first electronic computer, unveiled at the University of Pennsylvania in 1946. From that time until the 1970s, computers were big and expensive, requiring a team of experts to program and to operate. In the 1970s, a number of companies introduced much smaller and cheaper computers, which could fit on a desktop, and, on August 12, 1981, IBM introduced the PC-personal computer—the first truly practical desktop machine. Since then, the machines have grown cheaper and more powerful each year, and one is hard pressed to find a desk—in offices as well as homes—that doesn’t sport a PC.

In 1984, 18 percent of people over age 18 regularly used computers. In 1993, the figure was 36 percent. Significantly, 56 percent of children aged 3 to 17 regularly used computers in 1993.

The Internet is an international web of interconnected government, education, and business computer networks At last estimate, at least 25 million people access the Internet, which many regard as a kind of electronic community.
