e/German letter monopoly

Information
has gloss	eng: The Letter monopoly (German: Briefmonopol) was enshrined in the German law, and until the end of 2005 it granted an exclusive license to the German post office, Deutsche Post, for the transport of letters and catalog deliveries of up to 100 grams. For the period 2005--2007 this limit was reduced to 50 grams. In this way it provided a monopoly situation, even though only over a part of the postal market. The letter monopoly was often justified in connection with the provision of universal service by the state.
