LONDON — Jane Millichip has been upped to managing director of Sky Vision, the international distribution arm of pay TV outfit BSkyB.

She replaces Carl Hall, who is leaving Sky to set up Warehouse 51 Productions, an independent production company based in London. Warehouse 51 will focus on the production of factual and factual entertainment formats. Sky Vision’s production office in Bristol, England, will become part of Warehouse 51.

Millichip, who was director of sales and global brands at Sky Vision, joined the company in February from Zodiak Rights, where she was managing director.

Sky Vision’s head of programming and development, Danny Tipping, will continue to oversee Sky Vision Productions, which keeps its slate of specialist and popular factual television fare.

Sky Vision will work with Hall on the distribution of Warehouse 51 shows.

Hall sold his previous company Parthenon Entertainment to BSkyB in July 2012, and oversaw its integration and rebranding as Sky Vision. Since its launch, Sky Vision has expanded its programming portfolio into drama, comedy and entertainment, including series such as Sky Living’s “Doll & Em” with Emily Mortimer, and Sky 1’s drama “Moonfleet” (pictured) with Ray Winstone.

Hall said: “I’m extremely proud of Sky Vision and the way in which the team has created a high-class distribution capability within Sky. Sky Vision is ideally placed to grow and develop, and to help Sky realize the enormous potential that comes from being the fastest-growing source of investment in original British productions.

“However, I’m an entrepreneur at heart and having led Sky Vision for more than a year, and with a brilliant management team in place, I want to get back to what I know best. I am in a unique position to create a production house where top talent can get their ideas made and financed.”

Rob Webster, Sky’s commercial group director, added: “Having founded Parthenon and overseen its first year of operation as Sky Vision, Carl has helped embed an ambitious international distribution business within Sky, for which he has our sincere thanks.

“Carl leaves behind an extremely talented team and one which is well placed to build on what’s been a really positive first year for Sky Vision.”
