The source I used was “Film and Television Literature Index”. I selected this source because it had information on film and acting, something none of the other search engines, specialized in. It contains information about the film and television industry. From biographies to insider trade secrets it has a plethora of information. I found an article that talked about the salaries of production workers in the film and broadcasting business. The survey gave factual evidence of what professionals in this field reported they were paid. This survey is primary research because it is a survey that exhibits real salaries, with unbiased opinions. This is thus an example of primary research.
