The earliest online poker games were on IRC (Internet Relay Chat). Picture this: it is 1995, the internet is still dial-up, and you are sitting in a chat room negotiating a poker hand with people you do not know. Payments are conducted via check mailed to a mailing address or via Western Union wire transfer. There are no licensed casinos. There is no regulatory framework. It is basically underground poker played over the internet.
The first real online poker sites launched in the late 1990s. PokerStars was founded in 2001. Full Tilt Poker was founded in 2004. These sites were sophisticated enough to track hands, manage payouts, and handle thousands of players simultaneously. They were also legally questionable. The sites operated in jurisdictions with lax regulation, accepting US players despite the fact that online gambling law in the US was murky.
The Boom Years
Poker exploded in popularity after 2003. Chris Moneymaker, an amateur accountant, qualified for the World Series of Poker main event via an online satellite tournament on PokerStars. He won the tournament for $2.5 million. The story was irresistible: nobody to millionaire overnight via internet poker.
After Moneymaker's win, poker became mainstream. The World Series was broadcast on ESPN. Prime-time poker shows aired on cable. Online poker sites saw traffic increase tenfold. PokerStars became the dominant site. Millions of people who had never played poker in a casino opened accounts and started playing online.
The Legal Landscape
Throughout the boom, online poker operators were playing a legal game. The US had no explicit law banning online poker. The Unlawful Internet Gambling Enforcement Act (UIGEA) of 2006 was passed to restrict online gambling, but it focused on sportsbooks and casinos, leaving poker in a gray zone. The act prohibited financial institutions from processing payments for online gambling, but some payment processors found loopholes.
The Black Friday
On April 15, 2011, the US Department of Justice shut down the three largest poker sites: PokerStars, Full Tilt Poker, and Absolute Poker. The indictment alleged money laundering and illegal gambling operations. The sites were seized. Player funds were frozen. For US players, the entire online poker landscape collapsed in a single day.
The Aftermath
PokerStars and Full Tilt Poker eventually settled with the DoJ and returned player funds. But the damage was done. The sites were forced to exit the US market entirely. Recreational players who had been building bankrolls lost access. Professional players who had depended on online play migrated to other countries or transitioned to live casinos.
The Current Era
Online poker survives in the US only in regulated state-licensed markets like Nevada, New Jersey, and Pennsylvania. PokerStars operates legally in some states. Full Tilt operates in limited capacity. Internationally, online poker is booming. PokerStars is still the largest poker site globally. Players from Europe, Asia, and other regions can play without legal restriction.
What Changed
The move from IRC poker to PokerStars represented a shift from underground to mainstream. The move from Black Friday to regulated state poker represents a shift from unregulated to heavily regulated. Online poker today is not what it was in 2005. It is either regulated or it is illegal. There is almost no gray zone anymore.
The Significance
Online poker democratized the game. Before online poker, becoming a professional poker player required living in a place where poker games existed (Las Vegas, Atlantic City, cardrooms in California). After online poker, you could play from your bedroom. This enabled millions of new players and produced thousands of new professionals.
The legalization of online poker in some US states suggests that the regulatory environment might continue to open up. But the days of unregulated offshore poker are mostly over. The industry has matured and been incorporated into the licensed, regulated gaming framework.
