News stories must meet at least some of the criteria for publishing called news values.
These include:
Celebrity
Wealth
Sex
Oddity
Proximity
Race
As you can see, Tiger and his errant penis meet all these criteria.
Proximity is included because he's played golf in nearly all our hometowns, so he's therefore stayed at our local hotels where he potentially screwed one or more of our local cocktail waitresses and/or call girls.
The more of these news values the story has, the longer "legs" it has.
So you can plan on months more of Tiger the Whore news, which will eventually die down until he appears in public again.
Now that prescription drugs may be involved, he might start losing sponsors. Gatorade has already dumped its Tiger-inspired beverage.
And somehow I doubt that Nike's "Just Do It" campaign meant fucking around on one's wife.
