When Hotmail first started in the mid-90s, taglines helped people to discover our then revolutionary new type of personal email service … free web-based email. At the time, most people had an address tied to an ISP like an AOL, CompuServe, or Prodigy email, and taglines were an efficient way to let people know about Hotmail. As Hotmail evolved over the years, so did taglines, taking on the additional role of educating people about new features & services in Hotmail and other related products. They proved to be effective, with nearly 2 million taglines clicked per month.
