Beacon was a part of Facebook's advertisement system that sent data from external websites to Facebook, for the purpose of allowing targeted advertisements and allowing users to share their activities with their friends. Certain activities on partner sites were published to a user's News Feed. Beacon was launched on November 6, 2007 with 44 partner websites.[1] The controversial service, which became the target of a class action lawsuit, was shut down in September 2009. Mark Zuckerberg, CEO of Facebook, said on the Facebook Blog in November 2011 that Beacon was a "mistake".[2]

Privacy concerns[edit]

Beacon created considerable controversy soon after it was launched, due to privacy concerns. On November 20, 2007, civic action group MoveOn.org created a Facebook group and online petition demanding that Facebook not publish their activity from other websites without explicit permission from the user. In fewer than ten days, this group gained 50,000 members.[3] After the class action Lawsuit, Lane v. Facebook, Inc., Beacon was changed to require that any actions transmitted to the website would have to be approved by the Facebook user before being published.[4] On November 29, 2007, Stefan Berteau, a security researcher for Computer Associates, published a note on his tests of the Beacon system, and found that data was still being collected and sent to Facebook despite users' opt-outs and not being logged into Facebook at the time.[5][6] This revelation was in direct contradiction to the statements made by Chamath Palihapitiya, Facebook's vice president of marketing and operations, in an interview with The New York Times published the same day:

Q. If I buy tickets on Fandango, and decline to publish the purchase to my friends on Facebook, does Facebook still receive the information about my purchase?
A. "Absolutely not. One of the things we are still trying to do is dispel a lot of misinformation that is being propagated unnecessarily."[7]

On November 30, 2007, Louise Story of The New York Times blogged that not only had she received the impression that Beacon would be an explicit opt-in program, but that Coca-Cola had also had a similar impression, and as a result, had chosen to withdraw their participation in Beacon.[8]

On December 5, 2007, Facebook announced that it would allow people to opt out of Beacon.[9] Founder Mark Zuckerberg apologized for the controversy.

This has been the philosophy behind our recent changes. Last week we changed Beacon to be an opt-in system, and today we're releasing a privacy control to turn off Beacon completely. You can find it here.[10] If you select that you don't want to share some Beacon actions or if you turn off Beacon, then Facebook won't store those actions even when partners send them to Facebook.

On August 12, 2008, a class action lawsuit was filed against Facebook, Blockbuster Inc., Overstock.com, Fandango, Hotwire.com, GameFly, Zappos.com, and any additional "John Doe" corporations that activated Facebook Beacon when they released their common member's personal information to their Facebook user friends without their consent through the Facebook Beacon program. The lawsuit alleges the release of the information was a violation of the Video Privacy Protection Act, Electronic Communication Privacy Act, Computer Fraud and Abuse Act, California Consumer Legal Remedies Act, and the California Computer Crime Law.[11][12]

On September 21, 2009, Facebook announced that it would shut down the service.[13][14]

On October 23, 2009, a class action notice was sent to Facebook users who may have used Beacon.[15] The proposed settlement would require Facebook to pay $9.5 million into a settlement fund. The named plaintiffs (approximately 20) would be awarded a total of $41,000, and the plaintiff's lawyers would receive millions from the settlement fund.


Facebook Beacon worked through the use of a 1x1 GIF web bug on the third-party site and Facebook cookies.[16] Clearing Facebook cookies from the browser after explicitly logging off from Facebook prevented the third-party site from knowing a user's Facebook identity.

Partner websites[edit]

Beacon partner websites included:

Lawsuit and settlement[edit]

As part of a class action settlement, Facebook terminated Beacon. Facebook was also required by a court order to notify its users of the settlement. Facebook set up a $6 million[17] fund to establish an independent non-profit foundation that will identify and fund projects and initiatives that promote the cause of online privacy, safety, and security. Facebook also set up a website about the lawsuit. Under the contingency fee arrangement with the plaintiffs, the law firms that filed the case would get a fee, likely to be $3–$4 million, but the average Facebook user would receive no monetary award. Facebook notified its users about the court order.
