Desilu

Desilu Productions was a company jointly owned by American actors Lucille Ball and Desi Arnaz. It was home to such television classics as Star Trek, The Andy Griffith Show, Mission: Impossible!, and of course I Love Lucy.

Desilu's first studio was on Cahuenga Boulevard in Hollywood, at the site of what is now the Ren-Mar rental studio; the first episodes of I Love Lucy were filmed there. In 1956, the company bought the nearby RKO lot, and moved its facilities there.

Much of the studio's early success can be traced to Arnaz' unusual business style in his role as producer of I Love Lucy. For example, lacking formal business training, Arnaz knew nothing of amortization, and often included all the costs incurred by the production into the first episode of a season, rather than spreading them across the projected number of episodes in the year. As a result, by the end of the season, episodes would be nearly entirely paid for, and would come in at preposterously low figures. In addition, Arnaz took the unprecedented step of buying the episodes of I Love Lucy for an astoundingly low cost from CBS, realizing, as the network did not, the potential of the rerun.

After Arnaz and Ball's divorce in 1962, Lucy bought Desi's stake, leaving her in full control of the company. Later, in 1967, the company was sold to Gulf+Western, which merged it with its other production company (and Desilu's next-door neighbor) Paramount Pictures. Desilu's holdings are currently owned by media conglomerate Viacom.

The studio was named after Arnaz and Ball's ranch.
