For many years, a small minority of companies were considered to be in a regulated industry: medical, financial, automotive, etc. Those of us not in one of those industries looked at those companies from afar with envy and pity: how are they able to produce what they produce under the weight of those regulations?
Starting May 25, 2018, we will all be in a regulated industry. Those companies who do business in the EU and UK (and thus process data identifying their citizens) will be required to comply with the General Data Protection Regulation.
The data privacy principles espoused by the GDPR are not much different than those in the Directive 95/46/EC from 1995. However, the EU has concluded that nicely asking companies for 22 years to abide by those directives has not achieved the data privacy they require for their citizens. Therefore, creating the GDPR has given teeth to regulators in the EU and UK to enforce their data privacy principles and thus brings us all into a regulated industry.
