This trend continues year after year getting ever more ridiculous. In 2006 I wrote:
...the 3rd week of July and they already had some Halloween candy and Autumn decorations out. The shelf-life window for holidays keeps getting opened wider and wider. Where does it end? Holidays overlapping one another? Maybe we'll start to see holiday mash-ups. Wearing costumes and going house to house to exchange gifts. With the divorce rate what it is and the remarrige configurations getting more and more complicated many people are already do a house-to-house visitation style on Christmas. We already have the evil stepmothers why not add costumes. (Holiday Mashups)
It's a greedy "kill the goose that lays the golden eggs strategy" that retailers are engaging in. There is only so far you can stretch symbols and traditions before they break. They either become meaningless and collapse or become shells of their former selves. Santa could come simply to stand for "sale". The ultimate potential outcome is the destruction of Christmas. Which I find a rather delightful thought to entertain.
Anyone care to entertain a guess in which year Christmas will slam up against the 4th of July?
