Why are there always Christmas themed commercials still shown throughout January?

Question

Seriously, the holiday season is over now.  They can put these commercials off the air until after Halloween at least.  I’m still seeing Christmas/holiday commercials on TV a lot, I saw a few today.  One being the Liberty Mutual nostalgia commercial and another being the NFL Holiday themed commercial 

Answer 1

Because some people want to continue the holiday even though it’s over

Answer 2

They have to get rid of it all the commercial items left.
