Many people get their original inspiration to become a private eye from watching police crime dramas and detective investigation series on TV. For example, how cool was Tom Selleck, as Thomas Magnum, driving around the streets of Hawaii in a red Ferrari and living in a multi-million dollar mansion. In contrast, the police detective Colombo used quirky, but effective investigative methods to uncover the facts and solve crimes. In fact, my father got his inspiration to become a P.I. from watching James Garner in The Rockford Files.

In contrast to the shows of the 70’s and 80’s, the more modern shows such as Law & Order and NCIS inspire a new generation of crime scene investigation specialists.
