A lock-up period (especially in Anglo-Saxon or French-speaking area as well as in German-speaking Switzerland also embargo ) is a time- release lock for news and information. Retention periods are used when the media should be made available prior information or need to allow a subsequent in-depth coverage, but early release at the same time should be avoided. So also new releases of books will be given before the publication date of the reviewers. The secrecy associated with the locks ensures rumors and increases the market value of the message. Often holding periods are set to the early hours of the following day in order not to penalize print media.
News and information are marked with a lock-up period, should not be published before this period of media. However, the media must not keep it. Vesting periods are generally subject to the free agreement between informants and media and thus the relationship of trust between them. A fraction of the vesting period is therefore a breach of trust, but which is legally irrelevant, unless there are appropriate contractual agreement.
Often an editorial needs, the vesting disregarded, expect to be excluded from future advance information.
In Germany, the guidelines of the German Press Council until 2006 saw before, observed retention periods if it was objectively justified, for example in the text of a speech delivered or not at information about a not event occurring. In the directives were amended on 21 November 2006, the appropriate policy fell away. The Press Council, it is thus the responsibility of editors to observe embargoes or not.
