Start with a general search using your favorite search engine. Most sites will present current news for a business or industry.
- Company websites.
Most companies have their own websites. For larger companies, check for a media section where you'll find press releases and press kits. Don't underestimate the information that companies publish on their own websites. Just remember that a website is a marketing tool and most information you'll find on a company website will be positive.
- Directories and Yellow pages – On-line directory listings often offer many filtering options (e.g. by industry and region) and are even sometimes searchable by ZIP code.
- Historical information - The Wayback Machine (Archive.org) stores screenshots of websites over time. By looking at several old screenshots, you can see what a particular website looked like at a given moment in time, which is helpful when trying to identify a corporate strategy or future plans.
- Local Economic & Business Journals/Magazines/Newspapers are a good source for local company information. It's easy to find information on public companies, but a little trickier to find information on private companies. These websites often require registration, and some things are not free, but there is often a no-charge access level.
- National or International trade associations - Statistics, trends, competitors can often be found by researching the relevant trade association. Trade journals and publications, like local economic newspapers, also have information on industry trends and competitors.
