Computer software, mobile apps and online search services play a major role in the modern private eye’s business. Investigators use programs like case management to manage all of the information, data and materials related to a particular case.

Investigation professionals use online services to conduct research, run background checks, search databases and pull reports and data to find missing persons and uncover the truth about people. And detectives make heavy use of specialized applications (or apps) on their mobile devices to search for information on the go. Visit our Software, Mobile Apps and Online Services section.

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.

The introduction of crime scene forensics and DNA lab testing inspires many people to pursue a career in putting criminals behind bars. Check out our List of the Best Crime TV Series and Detective Shows for the definitive list of the most popular TV series, both old and new. All are available on DVD.

Visit our Government Research section to read helpful articles and learn more about how to leverage these helpful resources.
