EULA

Extracted from the Wikipedia article End-user license agreement.
Delivery of EULAs
Initially, end-user license agreement (EULAs) were printed on either the shrinkwrap packaging encasing the product (shrink wrap contract) or a piece of paper. The license often stipulated that a customer agreed if they did not return the product within a specified interval. After the advent of the internet, EULAs are more often found in clickwrap format where the user only needs to click an agree button. Without the constraints of having to print the license, the length of the agreements ballooned. Another type of license, browsewrap, intuits the user's consent after they simply visit a website and are made aware of the terms of use.
