The opening or lead paragraph is the most important paragraph of your
press release. Journalists will most likely decide by this paragraph
if they are going to read further.

When they read the opening paragraph, journalists should be able to 

answer the following questions, who, what, when, where and if necessary 

why and how.

There is no room for hype in the opening paragraph, stick to the
facts. A sample opening paragraph:
Company Name, a leading provider of (service/product) to (target
industry), today announced that (event).
