We launched this Review to take an objective, comprehensive look at the evidence. Likewise, our understanding of gambling-related harms and gambling disorder has developed enormously over recent years. Land-based gambling also finds itself in a very different place in light of these changes, with some of the assumptions which prevailed 18 years ago looking increasingly outdated. Newly available data and technology can both increase risks to players and facilitate innovative protections. Multinational tech businesses now provide gambling services which customers can engage with from almost anywhere and at any time of day or night. Few who were designing policy in the early 2000s could have foreseen the nature and extent of the changes which have since reshaped our society, the economy and this sector. The gambling landscape has changed significantly since 2005.
