The Package Travel Directive 90/314/EEC originates from 1990. Hence, it did not include all aspects of eCommerce when it came into force. However, in particular tourism services are not only suited for being displayed and edited on the Internet, but also for booking and conclusion of contract. Since then, the number of providers and offers in the World Wide Web has exploded. If in the initial stages, many consumers used the Internet mainly as a source of information, today booking their journeys via this medium is an everyday occurrence.
