Men to remember
  • Guglielmo Marconi is known as the Father of
    Radio. Marconi produced and detected waves

    foundations of the radio as we know it.

6
  • David Sarnoff created the
  • broadcast industry.
  • His first attempt to bring radio into the
    homes of millions was ignored in 1915. When he
    became General Manager of RCA in 1921 he seized
    an opportunity to give a blow by blow of
    Dempsey-Carpentier boxing match and it was a
    great success. The idea of broadcasting caught
    on.

    million people went to the movies each week. The
    movie palaces of the 20s were huge and lavish.
    Some really big theaters in places like New York
    and Detroit could seat up to 5000 people.

Improved Transportation
15
Lets Go Motoring
Model T
16
Henry Ford
  • Henry Fords assembly-line system drastically
    reduced the time it took to make a car and the
    amount it would cost. In 1920 a Model T cost
    roughly 800 but by 1925 it was reduced to 260,
    making very affordable to most. By the late
    1920s about 23 million cars were registered in
    the U.S.

17
A New Freedom
  • The automobile provided a new freedom to
    people. It allowed isolated farmers to travel
    into cities, workers find more affordable housing
    away from their jobs, and gave young people a
    chance to get out more.

18
Results of the automobile
  • 1- greater mobility
  • 2- creation of jobs (assembly line,
    construction)
  • 3- growth of auto related industries (oil, steel,
    road construction)

19
The Wright Brothers
  • In 1903 Orville and Wilbur Wright made the
    first engine powered flight. By 1929 planes were
    being used to carry passengers for profit.

Click the plane to find out how long the first
flight lasted.
20
Electrification
  • Electric lighting began to replace candles.
    Cities lit up first, followed by rural areas and
    by the end of the 1920s, most people had
    electricity.

21
Labor Saving Products
  • Because of electricity spreading and Fords
    perfection of the assembly line method, industry
    of the 1920s focused heavily on consumer goods
    that saved time on household chores.
  • Ex washing machines, refrigerators
  • stoves, vacuum cleaners
  • water pumps

22
Advertising
  • In 1850 the national annual income was about
    95 per person but had risen to 586 by 1918.
    With the increase of income there was also a
    powerful new business that emerged-modern
    advertising- to convince consumers to spend their
    money.

23
The psychology of buying
  • Advertiser's focused on the psychology of
    buying and ads soon appeared that appealed to
    peoples needs, frustrations, and anxieties.
  • See the following ads for example of how
    advertisers convinced people to buy a product

24
  • Listerine mouthwash pledged to save young
    people from the loneliness caused by unpleasant
    breath.

25
  • Holeproof Hosiery Company featured what were,
    for that time, a rather scantily clad young woman
    wearing the companys silk stockings saying,
    Make the public want what you have to sell.
    Make em pant for it.

26
  • Advertising played on womens fear of aging
    and losing their looks to sell their products.

27
Billboards
  • Because of the increase in the automobile,
    advertiser's used the billboard to reach many new
    consumers.

28
Effects of Advertising
  • Ex Listerine saw profits rise from roughly
    100,000 in 1920 to more than 4 million in
    1927.
  • It was a boom time for U.S. companies and the
    economy. For those who didnt have money on hand
    to buy goods, a solution was proposed that was
    irresistible at the time

29
Buying on Credit
  • The growth of the installment plan also fueled
    consumerism of the 1920s. These plans allowed
    people to buy goods on credit by paying a small
    amount down and then make monthly installments
    until it was paid off.
  • Ex a vacuum could be bought for 28.95. A
    consumer would pay 2 down and 4 a month.

30
Changing Role of Women
  • Womens roles in society changed a great deal
    during WWI and throughout the 1920s. After
    working in a traditionally male job during the
    war, it increased their motivation to be treated
    as equals. Women began to rally for better wages
    and more rights. After winning the womens
    suffrage movement there was a diminish in
    political interests and turned more towards a
    social life.

31
Fads Fashion
  • For many women the 1920s brought new freedoms
    and independence. There was more leisure time
    and money and women began to challenge
    traditional ideas of women's role in society.
    Womens fashions became an outlet or personal
    expression and there was more focus on womens
    body image.

Not everyone agreed with this new found freedom.

    see if they were showing to much leg. Chicago
    police are arresting a girl for indecent
    exposure in 1922.

34
Mens Fashions
  • Baggy knickers called plus fours after the
    yards of fabric needed to make them.

35
Flappers
  • Flappers were rebellious young women who wore
    short skirts, danced wildly, used cosmetics, and
    proudly displayed the signs of their
    independence, sexuality, and energetic youth.

36
Sports Mania
  • All areas of entertainment became
  • big business in the 1920s, and sports were no
    exception.
  • Baseball, college football, and boxing were
    spectacles for the masses.

37
The Babe
  • By 1927 Babe Ruth was a better-known American
    to most foreigners than President Coolidge. He
