The AP Stylebook editors announced these changes at the ACES2011 conference.
Effective as of 3 a.m. EDT Saturday, March 19, it will be:
• email, instead of e-mail. (Other “e” terms, such as e-book and e-commerce, retain the hyphen,)
• Kolkata, India, instead of Calcutta, India. To follow local style.
• cellphone, smartphone become one word. (No longer cell phone and smart phone.)
• handheld, n., hand-held, adj.
