Christmas and Easter??

i have noticed that when people show Christmas or Easter commercials they have nothing to do with the actual holiday. i see commercials or stores selling easter eggs and they have nothing to do with jesus or even christmas which the whole point of christmas is to celebrate jesus's birthday. it has nothing to do with elves and santa claus. for example the movie Santa Claus starring Tim Allen showed no celebration of Jesus birthday. santa claus is a christmas movie for crying out loud. these are Christian hoidays and they talk nothing about jesus. why is this? is it to make money through jesus's birthday by selling things like candy, movies, toys, etc....
