Email, you've come a long way, baby.

In its 40-year tenure as a form of communication, email has run its course from the domain of über nerdy computer scientists to one of the most common ways to keep in touch, both personally and professionally.

Although email as a mode of communication was around for ten years before the term "email" was actually coined, we now count on it in our daily lives. In fact, the use of email has become so pervasive that the Oxford English Dictionary recently added a slew of email acronyms to its official canon.

And finally, just this year, the AP Stylebook, a.k.a. the holy book of all (or most) journalists, amended the spelling of e-mail to email, allowing articles such as this one to save bigtime on hyphens.
