What does a fire stick do differently than using the apps on my TV?

I've always wondered what these are for.

Hard to say, guessing you have a newer "smart" tv. Roku and fire sticks are really helpful for streaming content if you have an older tv. Amazon promotes it to use with Prime video. I like BBC iPlayer and 4od.
