A common criticism of end-user licensing contracts is that they are often far too long for users to spend time reading them carefully. In March 2012, the PayPal end-user license agreement was 36,275 words and in May 2011, the iTunes agreement was 56 pages long.  The sources of information that reported these results stated that the vast majority of users do not read the documents because of their length. The applicability of an AEA depends on several factors, one of which is the court where the case is being tried. Some courts that have considered the validity of The Shrinkwrap Licensing Agreements have invalidated some EULA and have characterized them as liability contracts that are unacceptable and/or unacceptable according to the U.C.C – see z.B. Step-Saver Data Systems, Inc. v. Wyse Technology, Vault Corp. v. Quaid Software Ltd.  Other courts have found that the Shrinkwrap licensing agreement is valid and enforceable: cf. ProCD, Inc.
