[4] In September 1996, Brent Walker recouped £117m of the £685m it had paid for William Hill when Grand Metropolitan was found to have exaggerated the company's profits at the time of the sale.

[6] In February 1999, a proposed stock market flotation was abandoned due to "weak interest"[7] and Nomura sold the company to funds managed by private equity firms Cinven and CVC Capital Partners for £825m instead.

[2] The following year chief executive David Harding was awarded a £2.84m bonus, making him the UK's fifth highest paid company director in 2003.

The Office of Fair Trading made William Hill sell 78 of the 624 Stanley shops due to concerns over anti-competitive practices.

[12] In November 2008, William Hill went into partnership with Orbis (latterly OpenBet), and Israeli software company Playtech, to remedy its own failing online operation.

While on William Hill's payroll he tabled amendments to the 2003 budget proposing tougher levels of taxation for person-to-person betting exchanges.

[20] Under the terms of the deal, William Hill paid Playtech's founder Teddy Sagi £144.5 million for various assets and affiliate companies.

The operator was found to have accepted large deposits of cash linked to criminal activity between 2014 and 2016, resulting in £1.2 million in financial gains.

[29] On 17 July 2020, William Hill raised £224 million in a new ordinary share rights issue to provide a timely capital boost during the COVID-19 pandemic.

[31] On 30 September 2020, William Hill agreed to a £2.9 billion takeover bid by Caesars Entertainment, the Nevada-based casino operator.

[34][35] As Caesars was interested only in William Hill's industry expertise and its US operations, the European business was put up for sale, attracting bids from 888 Holdings, Apollo, and CVC.

Commenting on the penalty package, Andrew Rhodes, Gambling Commission chief executive, said: "When we launched this investigation the failings we uncovered were so widespread and alarming serious consideration was given to licence suspension.

However, because the operator immediately recognised their failings and worked with us to swiftly implement improvements, we instead opted for the largest enforcement payment in our history.

[56] The company's joint venture in Spain ended in January 2010 with partners Codere buying William Hill's 50% stakeholding for €1,[57] after both parties had invested an initial €10 million in April 2008.

[59] In June 2012, William Hill expanded to Nevada, the only U.S. state that then allowed full-fledged sports wagering,[60] buying three chains of sportsbooks: Lucky's, Leroy's, and the satellite operations of Club Cal Neva, for a total of $53 million.

William Hill entered arrangements to provide bookmaking services to both Monmouth Park Racetrack and Ocean Resort Casino in the state of New Jersey.

[66] On 3 August 2020, the bookmaker opened the first full-service betting operation housing professional sports teams in the U.S. at Capitol One Arena in Washington D.C.[67] In January 2021, a joint venture between William Hill and Argenbingo received a licence to offer online gambling services in the Argentinean province of Buenos Aires.

[74] In May 2008, The Advertising Standards Authority (ASA) banned William Hill from running a television advert which it found "condoned gambling behaviour that was socially irresponsible".

As part of the relaunch, the company launched a new TV advert featuring its brand ambassadors Tony McCoy, Robbie Savage, Rio Ferdinand and Jermaine Jenas and used the Neil Diamond song Sweet Caroline.
