Media can influence how we see things no matter what it is, relationships, food preferences, religions, political ideals, etc. The impact of media such as books or television or any other source can lead us to make a connection between what the media focuses on and whatever is happening in our lives.
An example here would be if you read. a story about a girl and her pet and you connect it to you and your pet. Whatever happens in the book may start to influence what you believe. For example if the dog in the book does a certain thing that is said to signify something, you as the reader may believe the same thing about your dog. This can also go the same for relationships wether they’re with a significant other, friend, or family member.
