Usage notes
This practice began with e-mail perhaps as far back as 1971. Many terms beginning with e- can be seen in both hyphenated (e.g. e-card) and unhyphenated (e.g., ecard) form, and sometimes — particularly in a business context — the letter following the e- will be capitalized (e.g., eBusiness or e-Business). In the present day, e- is generally used to indicate association with or transmission over the Internet. In proper names beginning with e-, the convention is generally to leave the e- lower-case, and to capitalize the second letter of the name (e.g., eBay). The e remains then lower-case when the name is used at the beginning of a sentence.
