What is the connection between snow globes and father christmas?

I watched the "Santa clause" series of films and they obviously have a magic snow globe but thought nothing of it. Then today I watched "the magic Christmas" (1980) and that has one in it too... I've then looked on line and realised they are advertised in stores everywhere. But I can't find any information why.

What is the link? Anyone know where the connection comes in/ started or how long it's been going???

I know it's not the most important thing but something I'd like to know!

Thanks

:-)
