The ICO has fined Facebook the maximum amount of £500,000 for the infamous Cambridge Analytica Data Breach. 

£500,000 is the maximum amount under the previous legislation (the previous legislation, the Data Protection Act 1998, is being used because the Cambridge Analytica scandal pre-dates the introduction of the GDPR). 

Data and privacy speculators are confident that under the GDPR, the amount of the wine would have been significantly greater - such speculation doesn't bode well for companies (including Facebook) that have had a breach whilst GDPR has been in force. 

It is reported that Facebook's global revenue tops $40 billion last year alone, which means that a fine under the current regime could have been $1.6 billion or £1.2 billion.
