In general, it's best to release news when it happens. Choose an angle. You can consider hanging your start by any of these angles.

The more company information the less likely you are to get published, but the more pure information, the less prominence to your company.

Provide useful hints about surviving in your industry or consumer hints such as how to judge the quality of a tomato, spiced with a little information about how the word tomato is said in different places, where the word comes from, or uses of the tomato internationally and so on.
