A web search engine is a software system that is designed to search for information on the World Wide Web.

The search results are generally presented in a line of results often referred to as search engine results pages (SERPs).

The information may be a mix of web pages, images, and other types of files.

Some search engines also mine data available in databases or open directories.

Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight.

It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention.

Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar.

Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens.

The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products.

Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses a private entertainment from a now enormous array of pre-recorded products; to a banquet adapted for two; to any size or type of party, with appropriate music and dance; to performances intended for thousands; and even for a global audience.

In publishing, art, and communication, content is the information and experience(s) that is directed towards an end-user or audience.

Content is "something that is to be expressed through some medium, as speech, writing or any of various arts".

Content can be delivered via many different media including the Internet, television, audio CDs, books, magazines, and live events, such as conferences and stage performances.

News is information about current events.

Journalists provide news through many different media, based on word of mouth, printing, postal systems, broadcasting, electronic communication, and also on their own testimony, as witnesses of relevant events.
