Why don't more people celebrate the 12 days?

 I've always wondered this. Why don't retailers start picking up bringing the 12 days into the public eye? It would be a big boom for them financially and I think the public would love celebrating a true 12 days instead of just one each year. 

I remember before we celebrated the 12 days, you felt a little deflated that it was all over all of the sudden. 

I see people throwing out their tree on Christmas night even! Are they THAT done with the holiday by then? I doubt there are that many people who would be against 12 days. 

These days it only takes one "trending" moment on social media to start a trend. Perhaps one day, someone will do just that and open up the knowledge about what the 12 days of Christmas are. 

I'm not that guy, in case you were wondering.
