A web chat is a system that allow users to communicate in real time using easily accessible web interfaces. It is a type of internet online chat distinguished by its simplicity and accessibility to users who do not wish to take the time to install and learn to use specialized chat software. This trait allows users instantaneous access and only a web browser is required to chat. Users will always get the latest version of a chat service because no software installation or updates are required.
History and technology
The history of web chatting is characterized by trends in underlying web technologies. The first chat sites featured simple interfaces made from dynamically generated HTML pages. The use of HTML allowed sites to incorporate fonts, colors, links, and images into their interfaces, giving them a more modern hypermedia feel, which was an advantage over older, but more established text-based chat services like IRC. The biggest downside to HTML chat was in its interactivity. Every message sent to an HTML chat required a form submission and subsequent page load, which meant that there was a waiting period between the time a user could send one message and the time they could begin to type the next one. Receiving messages also required frequent page reloads, and could lead to delays, page flicker and distracting browser activity. For these reasons HTML chats have largely fallen out of use today, although some of the older HTML chat sites still remain active.
In 1995, Java applet technology was introduced into web browsers. Java's well developed network and graphical capabilities made it an ideal platform for creating chat interfaces, some of which are in use on the most popular web chat sites today. While there are some drawbacks associated with Java chats such as long initial page loading times, the technology has worked well and scaled well.
Comparison with other chat services
Web chatting is only a small part of the world of online chat. Web chats do not have the same network effects as chat services like instant messengers, which become more useful as they become more popular. Smaller, less busy chats can actually have more appeal to users than crowded, popular ones. Really, the only unique feature web chat sites offer is instant accessibility. And in an internet where there are so many other choices for real-time social interaction: Internet Relay Chat networks, instant messenger services, online games, and virtual worlds. Web sites devoted to simple text-based chat remain a small, but singular phenonemon.
There are hundreds of web chat sites, which actively compete with each other to the point where some of the more popular ones actually censor the names of other chat sites, preventing users from referring each other to competing chats. The simple accessibility generates an extremely high level of competition between chat sites, as it allows users to switch between them with ease.
