I believe that small typography is often used to decrease readability in technical writing for pharmaceuticals. When a pharmaceutical company, such as mega corporation Gildead Sciences wants to sell a medication, they must highlight the benefits of the drug as much as possible, while limiting the attention given to negative side effects. Gilead Sciences is the current manufacturer of wonder-drug Harvoni, which cures Hepatitis C. Harvoni also sells for over a thousand dollars a pill, so a total three- month treatment cycle for Hep C would cost around $96,000. Because of this price, Gilead is especially calculative in presenting the side effects of Harvoni. For example, on their website below, the side effects are listed individually on the right side of the page, and they ask users to "scroll to continue" all the way to the bottom of the page, making it very tedious to read. http://www.harvoni.com/discover-harvoni/about-harvoni?utm_source=bing&utm_medium=cpc&utm_campaign=Search%20-%20Harvoni%20-%20Decision&utm_term=%2Bharvoni&utm_content=Harvoni%20-%20Broad&gclid=CPnp47jpqdACFVIngQodmacI3Q&gclsrc=ds
