It's like the HGTV effect. When we sold our house, everyone was looking for stainless and granite in the kitchen and "updated" (read huge) bathrooms. Never mind that stainless and granite always look dirty and that gi-normous master baths take up valuable floor space for a room you're only using an hour a day tops.
When I was racing boats, we always saw a bump in the numbers at the starting line the year after an America's Cup. You always see more joggers on the road after a Boston marathon. The following year it goes back to normal.
