definition of captive portal:
Captive portals are primarily used in open wireless networks where the users are shown a welcome message informing them of the conditions of access (allowed ports, liability, etc.). Administrators tend to do this so that their own users take responsibility for their actions and to avoid any legal responsibility. It is discussed whether this delegation of responsibility is legally valid. 
Often captive portals are used for marketing and commercial communication purposes. Access to the Internet over open Wi-Fi is prohibited until the user exchanges personal data by filling out a registration form. The online form either automatically opens in a device's browser, or appears when the user opens their browser and tries to visit any webpage. In other words, the user is "captive" - unable to browse freely until they accept the terms and conditions. This allows the provider of this service to display or send advertisements to users who connect to the WiFi access point. This type of service is also sometimes known as social WiFi, as they may ask for a social network account to login (such as Facebook). Over the past few years, such Social WiFi captive portals have become commonplace with various companies such as Aislelabs offering marketing centered around WiFi data collection.
The user can find many types of content in the captive portal, and it's frequent to allow access to the Internet in exchange for viewing content or performing a certain action (generally providing personal data to enable commercial contact); thus, the marketing use of the captive portal is a tool for lead generation (business contacts or potential clients)
