I am not sure if many know that tradition in the US but in Germany most children (and many older childs ) do have an "Adventskalender".
That is a calendar before christmas with some candy (often chocolate) in it for each day in December till the 24th.Every day you are allowed to open one "door" of it till xmas is there. (most people in Germany start celebrating christmas on the evening of 24th, not the 25th like in some other countries.
Anyway: This is the digital Adventskalender 2016 from my company. It is packed with funny, deep or just very nicely done commercials from all over the world and the cover art is done with A:M.
Have fun . Each day another door is openable :
