Following up on W2G's comments about the fleeting nature of publicity, and my negativity towards what's going on with horse racing, here's a couple charts that are somewhat telling.
The first is the google search volume of "horse racing" and "breeders cup." As you can see, the BC searches spike each fall, and immediately fall off. The somewhat scarier part of the chart might be that the horse racing trend line continues to be down.
And just to give some semblance of scale to compare, Here's the chart of the term "horse racing" versus "NFL." Notice that although seasonal, the NFL search term level continues to trend up each year.
And if we didn't feel bad enough already, I compared "horse racing" to "rugby," "cricket," and a few other somewhat obscure passtimes, and they all had higher search term traffic than "horse racing."
