Facebook has been around for so long now - you might not even remember a time before it.
In fact, for some of you reading this you may not have ever existed in a world without Facebook as the website celebrates its 20th anniversary. It has been around so long that it has seen many changes over its two decade existence.
Features have come and gone - some causing more of a splash than others. You may need to jog your memory more than a little bit to remember some. Drop me an email with your favourite: [email protected].

9. Facebook Beacon
Mark Zuckerberg himself referred to Beacon as a “mistake” - but what was it? It was a feature from 2007 to 2009 and was a key part of Facebook’s advertising strategy - and a precursor to Facebook Connect - but it was a bit of a PR nightmare. It was held responsible for ‘ruining Christmas’ because it would broadcast what people were buying online directly into their Facebook feed. It prompted a class action lawsuit which Facebook settled. | KIRILL KUDRYAVTSEV/AFP via Getty Images Photo: KIRILL KUDRYAVTSEV/AFP via Getty Images
