Drupal meets the needs of different types of web sites from community to news portals, from corporate sites to educational institutions, from media sites to international sites. Here are some case studies that showcase some of the ways Drupal has been applied:

Community Portal Sites If you want a news web site where the stories are provided by the audience, Drupal suits your needs well. Incoming stories are automatically voted upon by the audience and the best stories bubble up to the home page. Bad stories and comments are automatically hidden after enough negative votes. Examples: Fast Company | Team Sugar | Kerneltrap | Designer HK

News Publishing Drupal is great for newspapers and other news organizations. Examples: New York Observer (implementation info here) | Savannah Now | NowPublic | Popular Science

Aficionado Sites Drupal flourishes when it powers a portal web site where one person shares their expertise and enthusiasm for a topic. Examples: ia/ | Dirtbike

Intranet/Corporate Web Sites Companies maintain their internal and external web sites in Drupal. Drupal works well for these uses because of its flexible permissions system, and its easy web based publishing. No longer do you have to wait for a webmaster to get the word out about your latest project. Examples: AOL Corporate | Yahoo! Research

Resource Directories If you want a central directory for a given topic, Drupal suits your needs well. Users can register and suggest new resources while editors can screen their submissions. Example: Entomology Index

International Sites When you begin using Drupal, you join a large international community of users and developers. Thanks to the localization features within Drupal, there are many Drupal sites implemented in a wide range of languages. Examples: Christian Assemblies International | PuntBarra | cialog

Education Drupal can be used for creating dynamic learning communities to supplement the face-to-face classroom or as a platform for distance education classes. Academic professional organizations benefit from its interactive features and the ability to provide public content, member-only resources, and member subscription management. Examples: WPA | Amherst College | e-Learning Institute | DATC

Art, Music, Multimedia When it comes to community art sites, Drupal is a great match. No other platform provides the rock solid foundation that is needed to make multimedia rich websites that allow users to share, distribute, rate, and discuss their work with others of similar interest. As time goes on, Drupal will only develop stronger support for audio, video, images, and playlist content for use in multimedia applications. Examples: MTV United Kingdom | Sony Music | Terminus1525 | Project Opus | Warner Brothers records | Ads of the World | Vocalo.org

Social networking sites Drupal has many of common features used in social networking sites. You can build a collection of social networking applications around for your site or use Drupal as a white label social networking service. Examples: imbee | GoingOn | Jewcy | DrupalSN
