Analysis of Variance (ANOVA) and Tukey's HSD were used to determine differences among years. Random websites become progressively inaccessible through the years (p&lt;0.0001) [as shown by increasing Web Accessibility Barrier (WAB) scores], while complexity of the websites increased through the years (p&lt;0.0001). Pearson's correlation (r) was performed to correlate accessibility and complexity: r=0.463 (p&lt;0.01). Government websites remain accessible while increasing in complexity: r=0.14 (p&lt;0.041). It is concluded that increasing complexity, oftentimes caused by adding new technology to a Web page, inadvertently contributes to increasing barriers to accessibility for persons with disabilities.<\/jats:p>","DOI":"10.1145\/1029014.1028638","type":"journal-article","created":{"date-parts":[[2007,6,8]],"date-time":"2007-06-08T15:23:01Z","timestamp":1181316181000},"page":"32-39","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":20,"title":["Accessibility of Internet websites through time"],"prefix":"10.1145","author":[{"given":"Stephanie","family":"Hackett","sequence":"first","affiliation":[{"name":"University of Pittsburgh, Pittsburgh, PA"}]},{"given":"Bambang","family":"Parmanto","sequence":"additional","affiliation":[{"name":"University of Pittsburgh, Pittsburgh, PA"}]},{"given":"Xiaoming","family":"Zeng","sequence":"additional","affiliation":[{"name":"University of Pittsburgh, Pittsburgh, PA"}]}],"member":"320","published-online":{"date-parts":[[2003,9]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"100\n    Top Government Sites.
