Introduction
Modern online casinos have become a major part of the global entertainment and gambling industry. As of 2025, billions of dollars are spent every year on online slots, poker rooms, roulette, live dealer games, and sports betting platforms. But the journey from traditional, land-based casinos to today’s digital gambling platforms was not easy or quick.
This article covers the entire history of modern online casinos — from the early days of internet gaming in the 1990s to the rise of mobile betting apps, cryptocurrency casinos, and live-streamed dealer games. It also explains the key technologies, legal developments, and industry players who shaped the online gambling industry.

1. Gambling Before the Internet: The Foundation
Before the rise of the internet, gambling was limited to:
- Land-based casinos
- Betting shops
- Private poker rooms
- Horse racing and sports betting
- Government lotteries
The idea of gambling online was impossible before the 1990s, because:
- Computers were rare.
- Internet was not available to the public.
- Digital payment systems didn’t exist.
However, the demand for faster, more accessible gambling experiences was always growing.

2. Early 1990s: The Internet Revolution Begins
The 1990s changed everything. The internet became publicly available, and personal computers became cheaper. Businesses saw an opportunity to move services online — and gambling was one of them.
Key Milestone: Free Trade & Processing Act (1994)
- Passed in Antigua and Barbuda.
- Gave companies the legal right to apply for online gambling licenses.
- This law is considered the birth of the online casino industry.
First Online Casino Software Provider: Microgaming (1994)
- A company based in the Isle of Man.
- Created the first fully functional online casino software.
- Microgaming is still a leading software provider in 2025.
Security Provider: Cryptologic

3. 1996: First Real Online Casino Launches
InterCasino

Challenges Faced:

Still, the industry kept growing. More companies joined:

In 2006, the Unlawful Internet Gambling Enforcement Act (UIGEA) was passed in the United States.
What It Did:
- Made it illegal for banks and payment systems to process transactions for online gambling.

This law didn’t ban online gambling directly, but it caused:
- Loss of revenue for companies.
- Shift of operations to Europe and Asia.
- Rise of offshore gambling sites not regulated by the US.
