What about using the company's own website as a source of information? There is no question that it can be a useful source to find out what is happening at a company, to learn about products, divisions and other basic information. It is important to keep in mind that the company site is primarily a public relations document, designed to encourage investors to buy stock. Therefore you need to carefully evaluate the information found on the web site, and keep in mind that the company isn't likely to offer any information that isn't positive. In other words, the company's own web site has internal biases that make it a fine starting place, but best augmented by the resources available to you as a TJU student.
You can also check YouTube and a company's Instagram feed for information about a company.
