In the world of entertainment, TV talk shows have undoubtedly flooded every inch of space on daytime television. (1) But no two shows are more profoundly opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey show.
Jerry Springer could easily be considered the king of"trash talk". (2) For example, the show takes the ever-common talk show themes of love, sex, cheating, guilt, hate, conflict and morality to a different level. (3)
Like Jerry Springer, Oprah Winfrey takes TV talk show to its extreme, but Oprah goes in the opposite direction. (4) Topics range from teaching your children responsibility, managing your workweek, to getting to know your neighbors.
Compared with Oprah, the Jerry Springer show looks like poisonous waste being dumped on society. Jerry ends ever with a "final word". (5) Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. (6) Most of these people have the time, money, and stability to deal with life’s tougher problems. Jerry Springer, on the other hand, has more of an association with the young adults of society. (7) They are the ones who see some value and lessons to be learned underneath the show’s exploitation.
While the two shows are as different as night and day, both have ruled the talk show circuit for many years now. (8) Ironically, both could also be considered pioneers in the talk show world.
  • A. He makes a small speech that sums up the entire moral of the show.
  • B. The show focuses on the improvement of society and an individual’s quality of life.
  • C. The show’s main target audience are middle-class Americans.
  • D. Each one caters to a different audience while both have a p following from large groups of fans.
  • E. The topics on his show are as shocking as shocking can be.
  • F. These are 18-to 20-year-olds whose main troubles in life involve love relationship, sex, money and peers.
  • G. And anyone who watches them regularly knows that each one varies in style and format.
  • H. Clearly, the Jerry Springer show is a display and exploitation of society’s moral catastrophe, yet people are willing to eat up the intriguing predicaments of other people’s lives.
