There are 500 Million Facebook users.
The Wall Street Journal reported that your information was being transmitted to marketing firms.
In response, U.S. Representatives Edward Markey (D-Mass) and Joe Barton (R-Texas), sent a letter to Facebook CEO, Mark Zuckerberg.
The WSJ noted an excerpt from that letter which expressed concerns that "third-party applications gathered and transmitted personally identifiable information about Facebook users and those users' friends."
The letter requests that Mr. Zuckerberg provide information such as: 1. how many people were affected; 2. when Facebook knew about it; and 3. permanent changes Facebook will make to prevent further issues.
The response is due next week on 10/27!
