Through content analysis, scholars strive to answer the questions first formulated by political scientist Harold Lasswell as they apply to health and medicine texts: “Who says what, to whom, why, to what extent and with what effect?"[58] For example, researchers might study the content of pharmaceutical advertisements on television to determine their appeals to potential consumers.[59] Others might examine the communication of health information via new media such as Twitter[60] and Facebook.[61] Rhetoricians have increasingly turned to computers to facilitate quantitative content analysis as they gather massive data collections from Internet sources.[62]
