Sports betting has been around for quite some time before the advent of screens and algorithms. For the majority of the history of sports betting, making a bet meant going into a store, writing out a paper slip, and handing over cash.
The scene from the past seems like something out of a different world. Now the odds change with each second, and the money is transferred into digital wallets within minutes.
The Era of Paper Betting Slips
Licensed betting shops soon began to appear on the UK landscape from May 1, 1961, as the Betting and Gaming Act of 1960 paved the way for off-course cash betting. In less than half a year, more than 10,000 were up and running. Before legalisation, the system ran on trust and risk:
- Runners were used by street bookmakers to convey odds and collect bets, avoiding detection by the police under the Street Betting Act 1906.
- The richer punters who bet on credit by phone, which is legal, but only available to those with a phone and a bookmaker account.
- Factory runners also took bets informally between shifts, working in a grey area that law enforcement, for the most part, looked the other way from.
The 1960 Act placed these activities under regulation, and the whole system remained analogue for a while. The bets were placed on boards and were changed only a few times a day, at most.
Telephone and Early Digital Betting
Telephone betting services have their roots in the 1960 Act. However, in the 70s and 80s, the service model was further developed. Large bookies like William Hill, Ladbrokes, and Coral established telephone call centers where people could open accounts. The technology was also further developed. Instead of handwriting on boards, computerized odds systems were used in the larger organizations during the 1980s.
The Online Betting Boom (2000s–2010s)
Intertops launched what is considered the first genuine online sportsbook way back in 1996. In 1998, there were a hundred betting sites running globally. Not long after, the UK-based bookmakers launched their very own ones. Three changes reshaped the business during the 2000s:
CHANGE | WHAT IT MEANT | ||
|---|---|---|---|
Live (in-play) betting | Odds shift during the match, and bettors can wager | ||
Digital wallets and payment gateways | Deposits and withdrawals via Paypal, Skrill, and Neteller | ||
Created the Gambling Commission, introduced licensing | |||
By the late 2010s, the annual turnover of global online bookmakers reached billions of dollars. Now casino has achieved similar success.

Mobile Betting and Instant Access
In the early 2010s, smartphones transferred betting from computer screens to our pockets. Operators such as FanDuel, DraftKings, Bet365, and many more launched apps, utilizing location technology via GPS, push notifications for live betting, and cash-out buttons. Today, mobile accounts cover more than 70% of online betting in mature markets.
Data, AI and Personalisation
Modern sportsbooks run on data feeds that update odds multiple times per second during live events. AI also handles the user-facing side:
- Recommendation engines suggest bets based on a user’s history and preferences.
- Automated risk models flag unusual betting patterns in real time.
- Cash-out pricing adjusts dynamically using the same models that set the original odds.
The line between watching sport and betting on it has blurred. Broadcasters embed odds into streams, and sportsbook apps carry live video.
Regulatory Evolution
Regulation has struggled to keep pace with technology. The UK Gambling Act 2005 was one of the first sets of rules designed specifically for operators in the online space. Responsible gambling tools are now standard across licensed platforms:
- Deposit limits and cooling-off periods are set by the user.
- Self-exclusion registers (GamStop in the UK, state-level programmes in the US).
- Mandatory affordability checks triggered by spending patterns.
From old-fashioned handwritten slips through real-time bets based on AI-calculated odds, the technology has advanced beyond the regulations for several years. Now, governments are catching up the progress while at the same time liberalizing business licenses.
