Well, you’re a bit off, they do make you want to buy their product, just indirectly
Most of these are used for what is called “brand recognition”. They just want you to know who they are, this particular ad isn’t directly a sales pitch, but they want you to know who they are so that may influence a purchase decision in the future. They want to make sure you constantly know they are out there on the market. Brand Recognition is a thing that works, over and over, marketers show that this works. Its also a HUGE buzzword in marketing too… so yup.
For many brands, this is a major portion of how they advertise.
