The History Of Online Poker, Other types of online gambling sites were launched before the first online poker room. Online sports books were introduced in the mid 1990’s which was also the time of online casinos sprouting up around the web. It wasn’t until 1998 that the first online poker forum was launched. Planet Poker, which has since become a relatively small poker room, enjoyed the status as the sole online poker forum for a short period of time. Other online sites entered the fray soon after.
