NCIS: Los Angeles, one of the longest-running primetime scripted shows for CBS, will soon come to an end with its current season 14. The decision to end the show was reportedly based on the significant cost of the long-running drama. The series finale, airing on May 14 and 21, will feature G. Callen and Anna Kolcheck's wedding. The finale will also include a one-hour special celebrating the show's 14-year history. While NCIS: Los Angeles is ending, the original NCIS has been renewed.
