Personalization: Personalization involves using technology to accommodate the differences between individuals. Once confined mainly to the Web, it is increasingly becoming a factor in education, health care (i.e. personalized medicine), television, and in both business to business and business to consumer settings. Web pages are personalized based on the characteristics (interests, social category, context, etc.) of an individual. Personalization implies that the changes are based on implicit data, such as items purchased or pages viewed.
