If you’re looking to write a press release then you might find the following structure useful.
Who are the key players — your company, anyone else involved with the product? Who does your news affect/who does it benefit?
What is new?
Why is this important news — what does it provide that is different?
Where is this happening/is there a geographical angle/is the location of business relevant?
What is the timing of this? Does this add significance?
How did this come about?
