William Hill, which currently derives 20 percent of its gross revenue from Internet gambling bets, expects that gross revenue to grow by 50 percent once its new online sportsbetting platform is launched.

William Hill's online sportsbook has been struggling over the past year due to intensifying competition and technology problems. It attempted to implement a major upgrade to its Internet betting operations in-house but was forced to scrap the project and write-off over $42 million. It then turned to Orbis, which already serves clients including Ladbrokes and Paddy Power.
