EDIT: I stand corrected! Multiple "Apple Original Series" contain Apple products, such as in Ted Lasso and (I think implied) in For All Mankind, as people pointed out below. Shows what I know about TV.
I wonder why some Apple Original Series have Apple products, and some don't. I would love to see if there's any correlation between the number of shows which feature a specific product and that product's market share in the show's region or demographic.
