Final answer:
The right to be forgotten was implemented in the European Union, under the General Data Protection Regulation (GDPR), which provides strict data protection for individuals.
Step-by-step explanation:
The right to be forgotten, a concept that protects individual information during searches, was primarily implemented in the European Union (EU). Under the EU General Data Protection Regulation (GDPR), citizens are granted comprehensive protection for their personal data. Private businesses and government agencies within the EU are subject to strict rules regarding the collection and processing of this data, ensuring that it may only be done in specific, allowable instances. This contrasts with other regions, like the United States, where the balance between national security and individual privacy rights has tipped towards more relaxed data protection due to the passage of laws such as the USA PATRIOT Act.
