December 2018: Facebook comes under fire after a company discovered that the company allowed more than 150 companies, including Netflix, Spotify and Bing, to access unprecedented amounts of user data, such as private messages.
Some of these & # 39; partners & # 39; had the ability to read, write and delete personal messages from Facebook users and to see all participants at a discussion.
It also allowed Microsoft & # 39; s search engine, known as Bing, to see the name of all friends of Facebook users without their permission.
Amazon could obtain the names and contact details of users through its friends and Yahoo could view streams of messages from friends.
From last year, Sony, Microsoft and Amazon were all able to obtain email addresses from users through their friends.
September 2018: Facebook revealed that it was hit by the largest ever data breach, affecting 50 million users – including that of Facebook boss Mark Zuckerberg and COO Sheryl Sandberg.
Attackers took advantage of the & # 39; View As & # 39; feature of the site, which allows people to see what their profiles look like for other users.

The unknown attackers used a function in the code & # 39; Access tokens & # 39; to take over people's accounts, potentially allowing hackers access to private messages, photos & messages – although Facebook said there was no evidence that it was done.
The hackers also attempted to harvest personal information from people, including name, gender and place of birth, via Facebook's systems.
Facebook said it does not yet know if information from the relevant accounts has been misused or has been used and is working with the FBI to investigate further.
However, Mark Zuckerberg assured users that there was no access to passwords and credit card information.
As a result of the infringement, the company removed around 90 million people from their account as a security measure earlier today.
March 2018: Facebook made headlines earlier this year, after data from 87 million users had not been used correctly by Cambridge Analytica, a political consulting firm.
The disclosure has prompted government inquiries about the company's privacy practices around the world, and has sparked a & # 39; # deleteFacebook & # 39; movement among consumers.
The Cambridge Analytica communications company had offices in London, New York, Washington, but also in Brazil and Malaysia.
The company can boast of finding your voters and putting them into action through data-driven campaigns and a team that includes data scientists and behavioral psychologists.
& # 39; In the United States alone, we have played a crucial role in winning presidential races and in congress and state elections & # 39 ;, Cambridge Analytica claims on its website with data on more than 230 million US voters.
The company benefited from a feature that meant that apps could request permission to access your own data, as well as the data from all your Facebook friends.

This meant that the company could extract the information from 87 million Facebook users, although only 270,000 people gave their permission to do so.
This is designed to help them create software that can predict and influence voters' choices at the polls.
The data product suspended its president, Alexander Nix, after the recordings of him emerged making a series of controversial claims, including that Cambridge Analytica had a pivotal role in Donald Trump's election.
This information is said to have been used to support the Brexit campaign in the UK.
It has also suffered several previous problems.
In 2013, Facebook unveiled a software issue that exposed 6 million phone numbers and email addresses of users to unauthorized viewers for a year, while a technical failure in 2008 revealed confidential birth data on 80 million Facebook user profiles.
