question / pregunta:
Are there statistics available to show how much revenue each of the Fortune 500 (or the Standard & Poor's 500) companies received from the federal government in a given year? For example, how much of IBM's revenue came from the federal government in 2010? And so on.... I think it would be possible to collect this information from publicly-traded companies, and I would like to know if someone has already collected this kind of information, and if so, where to find this information.
