There's a couple of approaches you can try;
- Be the contrarian
- The news hook - tie in with current events
- The attack (if you're up to it)
- Be a resource - offer content of value
- A humouristic approach
Keep in mind that depending on what else is happening, your story can get burried.
Tips:
Mid week is better time to submit
Include contact info on a news release (and be available)
Don't submit after 2 pm (be aware of time zones when submitting)
Lead your relase with the who, what, where, when, why in the opening paragraph
Your news release headline will make or break your chances of getting picked up
