Good informative speech topics for a college student include the popularity of reality television, a history of women in the military, the history of a comic character and the history of Barbie. It is important to remember the speaker need not be persuasive, only informative while speaking.
Reality television is a relatively recent phenomenon, and it may be easy to lay out a history of it. Women in the military may be a surprising topic for listeners due to its long history. The popularity of comic-related movies may make an audience eager to hear about a favorite character. Similarly, pleasant childhood memories of products, such as Barbie, may make them curious about the longer history of the product.
