After what some in the poker industry are calling "Black Friday", October 13th, when US President George W Bush signed into law legislation that shook up the world of online poker, some online poker rooms have actually benefited while others suffer. Many online poker rooms, mostly those that are publicly traded on stock exchanges, have left the US market, driving their former customers to those who have stayed behind. Poker Stars, already one of the top performers in the industry, has shot to the top of the billing thanks to the influx of American poker players looking for a safe port in the storm.
