The Libraries pays for the databases that appear on the first page and makes them available to students at no cost. There are many things that can only be found in one of these subscription databases. However, there are also quite a few things you can find on the web that will be very useful in providing evidence or support for your project proposal.
Another great source of information about both an industry/product and the consumers who use it is a trade or professional association web site. The members of these associations are people who either work in or are interested in what is happening in a particular industry. Although a majority of the information on the web site is only available to these (dues paying) members, in some cases there are free white papers, excerpts of larger (expensive) reports, etc.
Just enter the name of your product/service/industry into your favorite search engine along with the word "association' to identify relevant sites.
Here is an example: American Beverage Association
You might be able to find useful information on a company's web site (either your own company or a competitor), keeping in mind that the information provided by the company itself is likely to be somewhat biased. Usually just searching by company name in your search engine will take you to the corporate site.
Public companies (i.e., those that have held an initial public offering and whose shares are traded on a stock exchange) are required by law to disclose a great deal of information to the government and their stockholders. You will find their web sites to be more useful than those for smaller, private, and/or subsidiary companies who share only as much information about themselves as they choose.
Compare the available info for these two cosmetics companies:
Note: If a company is public, look for a link on the main page (near the very top or very bottom) labeled "Investors" or "Investor Relations." This will take you to a page containing all sort of corporate information, including links to the 10K and annual reports and press releases.
Market research companies produce very detailed studies and reports on a wide variety of products and consumers. Sadly, the majority of these reports are more than you (and even the Libraries) can afford.
However, several of the major market research companies provide snippets or summaries of these uber expensive reports on their web sites, typically in the "newsroom" or "press" or blog section of the site.
You can search these sites to find things that mention your target market, your product/service or media usage.
