Then and Now: The History of TDD. Drew shows the old TDD that weighted heavy that he cannot move the TDD. Drew then calls for his assistant, Werd to assist with describing the history of TDD and how it changed over time. Drew then shows different models of TDD and it got smaller and more light than previous models. Now, the rise of technology means that deaf people use AIM and pagers to stay in touch.
