  1. When a television program no longer receives enough viewers as they want it to have, the television network that is broadcasting the tv show will decide to cease purchasing additional episodes of the program. When this happens a show is "cancelled." In some cases a cancelled show may continue on as a privately sold program in Syndication. One example of this is the tv program "Baywatch."

  2. Colloquially, when an insurance company decides to refuse to renew coverage on someone, typically with automobile insurance, it is said that the insurer has "cancelled" their insurance. Technically, insurance is only "cancelled" if an insurer immediately notifies someone that they are terminating coverage.

  3. When a message, also known as an article is posted to a Usenet news group and subsequently the poster wishes to revoke or take back the message, they send a cancel request to have the message cancelled.

  4. When an item of value such as a check or a ticket has been redeemed for the face value or otherwise used, the item is marked non-reusable or "cancelled."
