For practical reasons, most news servers have different categories for different classes of postings: for example, the "announce" newsgroup for the ISP or other agency providing the news server may retain postings either for a very long time or indefinitely, whereas postings in binary newsgroups are usually not retained for long due to the storage requirements involved.
  5. In the United States court system, judicial retention is a process whereby a judge is periodically subject to a vote in order to remain in the position of judge.
  6. In organizations, keeping personnel within the organization from departing.
