Since the closing of the 20th Century, the 1920s has drawn close associations with the 1990s, especially in the United States. This due to the fact both decades were considered very economically prosperous times, and a prosperity which lasted throughout almost the entire decade following a tremendous event at the closing of the previous decade (World War I and Spanish flu in the late 1910s, and the end of the Cold War in the late 1980s). In Australia, this decad ...

| | | | 1920s - Technology: Encyclopedia II - United States technological and industrial history - Post-Civil War industrialism During the last half of the nineteeth century, after the American Civil War, United States industry began to boom at an unheard-of rate. Northern business entrepreneurs flourished - their main domestic rivals, the Southern planter class, no longer had political power, the tariff was high, and government on every level was eager to see the expansion of business. The changes that these innovators created in American society had a swift and dramatic influence.

Aircraft used commercial AM radio stations for navigation. This continued through the early 1960s when VOR systems finally became widespread (though AM stations are still marked on U.S. aviation charts).
In the early 1930s, single sideband and frequency modulation were invented by amateur radio operators. By the end of the decade, they were established commercial modes.
Radio was used to transmit pictures visible as television as early as the 1920s. Standard analog transmission ...

| | | | 1920s - Technology: Encyclopedia II - Roaring Twenties - Economy of the 1920s The Roaring Twenties were traditionally viewed as an era of great economic prosperity driven by the introduction of a wide array of new consumer goods. Initially, the North American economy, particularly the economy of the USA, took sometime to convert from a wartime economy to a peacetime economy. After this dull phase, the economy was booming. The decade saw North America becoming the richest region on the earth, with industry aligned to mass production, and a society with a culture of consumerism. In Europe, the economy did not start to flourish until 1924. At the same time the 1920s were setting the stag ...

Roaring Twenties - Warren G. Harding.
Warren G. Harding ran on a promise to "Return to Normalcy", a term he coined, which reflected three trends of his time: a renewed isolationism in reaction to World War I, a resurgence of nativism, and a turning away from the government activism of the reform era. Throughout his administration, Harding adopted laissez-faire policies. Harding's "Front Porch Campaign" during the late summer and fall of 1920 captured the imagination of the country. Not only was it the firs ...

Roaring Twenties - Immigration laws.
The United States, and to a lesser degree Canada, became more isolationist during the Roaring Twenties. The American Immigration Act of 1924 limited immigration from countries where two percent of the total U.S. population, per the 1890 census, were immigrants from that country. Thus the massive influx of Europeans that had come to America during the first two decades of the century slowed to a trickle. Asians and citizens of India were prohibited from immigrating altogether. ...

Roaring Twenties - Black Tuesday.
The Dow Jones Industrial Stock Index had continued its upward move for weeks, and coupled with heightened speculative activities, it gave an illusion that the bull market of 1928 to 1929 would last forever. On 29 October 1929, also known as the Black Tuesday, stock prices on Wall Street collapsed, setting off a chain reaction of bankruptcies and defaults that quickly spread overseas. The events in the United States were the final shock in a worldwide depression, which put millions of people out of work across the capitalist world throughout ...
