Mr. President has already started working with William Hill’s ad agency Fabula to manage an online competition where viewers can win a free bet if they can #SpotTheFACup in an image.
This weekend as the FA Cup is down to four teams the Fabula-created William Hill idents will show the cup hidden in each of the four semi-finalists’ grounds.
Moving forward, Mr. President will be responsible for overhauling William Hill’s social media presence and work closely with Fabula on a campaign around sports.
Kristof Fahy, the chief marketing officer at William Hill, said: "William Hill is already a huge online business, and this appointment is all about helping us to get better at reaching our customers in digital channels and building our brand with new audiences.
"Mr President have exceptional experience in this space and are a welcome addition to the team"
In October 2012 William Hill split its £14 million UK advertising account, appointing the start-up Fabula to handle the sports-betting side of the business and retaining the incumbent Beattie McGuinness Bungay for its gaming products.
