During the 1990s, online games started to move from a wide variety of LAN protocols (such as IPX) and onto the Internet using the TCP/IP protocol. Doom popularized the concept of deathmatch, where multiple players battle each other head-to-head, as a new form of online game. Since Doom, many first-person shooter games contain online components to allow deathmatch or arena style play. And by popularity, first person shooter games are becoming more and more widespread around the world. And FPS (First Person Shooter) games are now becoming more of an art form because of the required skills and strategy with teammates. More first person shooter competitions are formed to give players a chance to showcase their talents individually or on a team. The kind of games that are played at the more popular competitions are Counter-Strike, Halo, Call of Duty: Modern Warfare 3, Quake Live and Unreal Tournament. Competitions have a range of winnings from money to hardware.
