of online gaming. Nintendo also has a network, dubbed "Nintendo Network", that fully supports online gaming with the Wii U and Nintendo 3DS. Browser games As the World Wide Web developed and browsers became more sophisticated, people started creating browser games that used a web browser as a client. Simple single player games were made that could be played using a web browser (most commonly made with web technologies like HTML, JavaScript, ASP, PHP and MySQL). The development of web-based graphics technologies such as Flash and Java allowed browser games to become more complex. These games, also known by their related technology as "Flash games" or "Java games", became increasingly popular. Games ranged from simple concepts to large-scale games, some of which were later released on consoles. Many Java or Flash games were shared on various different websites, bringing them to wide audiences. Browser-based pet games are popular among the younger generation of online gamers. These games range from gigantic games with millions of users, such as Neopets, to smaller and more community-based pet games. More recent browser-based games use web technologies like Ajax to make more complicated multiplayer interactions possible and WebGL to generate hardware-accelerated 3D graphics without the need for plugins. Types of interactions Player versus environment (PvE) PvE is a term used in online games, particularly MMORPGs and other role-playing video games, to refer to fighting computer-controlled opponents. Player versus player (PvP) PvP is a term broadly used to describe any game, or aspect of a game, where players compete against each other rather than against computer-controlled opponents.

Doom popularized the concept of a 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. As games became more realistic and competitive, an e-sports community was born. Games like Counter-Strike, Halo, Call of Duty: Advanced Warfare, Quake Live and Unreal Tournament are popular with these tournaments. These tournaments have a range of winnings from money to hardware. Expansion of hero shooters, a sub-genre of shooter games, happened in 2016
