By way of an EU regulation adopted by the Council and European Parliament, the European Commission, European Parliament, and Council of the European Union reached an agreement on February 14, 2019 to implement new rules designed to ensure a fair, transparent and predictable business environment to both end consumers and entrepreneurs using third party online platforms for their business. An example of this includes hotels that offer rooms through booking platforms or app developers who distribute their software through app stores.
