Useful industry information for academic business studies that is both free and online is difficult to find. Most useful online industry information must be paid for in some way because of the time, effort, and hierarchical industry classification system required to collect and group company data into industry information.

The video below shows how to search for NAICS Codes and how to find free government data and data offered through NEIU Libraries.
