When researching a product or a market, it is helpful to first understand the broader industry and the companies involved in it.
IBISWorld: Comprehensive industry profiles covering about 800 different U.S. industries. IBISWorld uses the federal government's North American Industry Classification System (NAICS) to classify the industries it covers. To find an industry profile, you can browse through the 700+ NAICS codes or you can use the IBISWorld search function to identify an industry by keyword, company name or a specific code.
Marketline: Industry profiles for many industries in the U.S. and many foreign countries. Reports are updated annually. You can browse a list of industries or use the search box to search for an industry by keyword. Because Marketline is international in scope, you will usually find profiles of industries in a number of countries or regions of the world.
