By the late 1920´s a new opposition mobilized nationwide.

Coca-Cola serves as a good example of how product advertising changed over a forty-year period. When first introduced in the 1880´s, the product was marketed as a medicine, with claims that it cured headaches, and that it "revived and sustained" a person. Seeking to build repeat business and brand loyalty, by the 1920´s the company emphasized it as a refreshment and a "fun food". Consumers demanding the cola at soda fountains could pressure store owners to stock it, or risk losing their business.

The traditional jazz band was composed primarily of brass instruments and was considered a symbol of the south, but the piano was considered an instrument of the wealthy. With this instrumental modification to the existing genre, the wealthy blacks now had more access to jazz music.

Seeburg combined an electrostatic loudspeaker with a record player that was coin-operated, and gave the listener a choice of eight records. This Audio-phone machine was wide and bulky, and had eight separate turntables mounted on a rotating Ferris wheel-like device, allowing patrons to select from eight different records. Jukeboxes were most popular from the 1940´s through the mid-1960´s, particularly during the 1950´s. By the middle of the 1940´s, three-quarters of the records produced in America went into jukeboxes.

The essential part of a 1920´s man’s wardrobe was his suit. For day, evening, office, or parties, a man always wore a suit. What sets 1920´s men’s suits apart from other decades are the material and fit. Suits were mostly made of thick wool or a wool tweed, and pants made of wool based flannel that made them heavier than today’s suit materials but lighter than the previous decades. Suit jackets were either single or double breasted and featured 3 or 4 buttons up the front.

Tiger Flowers was the first African-American middleweight boxing champion, defeating Harry Greb, a whiter boxer, and claiming the title in 1926. During the decade, Jim Crow laws prevented most gifted black athletes from participating in the American Dream of success that was so much a part of the sports culture. Convinced that a mixed boxing match would have little gate appeal, many white boxers refused to face black fighters or, if they did, virtually required the African American fighters to lose.
