There's probably not an up to date accurate list, for several reasons: 1) It's a moving target - companies change what they collect. 2) Especially for large companies like Facebook or Google, the data collected by different business units may be different - that's part of why Google's privacy policy was so hairy for a while. 3) Some information may be gathered indirectly - for instance, geolocation information, your ISP/employer (as intuited from IP->ASN translations), and data collected by third parties (run NoScript sometime, and look at how many sites load Javascript from tons of other sites). 4) Similar to 3 - third-party cookies and other tracking. Get the Collusion plugin for Firefox, and be prepared to be amazed. 5) Keep in mind that many of these companies (and basically 100% of those who provide any "free" service) consider the data to be valuable business assets that they intend to monetize and not share - when your business model depends on being able to correlate the type of music you download with how often you visit Wikipedia, you're going to try *really* hard to avoid letting anybody find out that you're tracking music downloads and Wiki hits.
