Suggestive Marketing

I am curious about the affect suggestive marketing is having on today's economy. Have you ever noticed that when you search for something online, the internet recognizes it and adds relating to your search continue to pop up. They are trying to narrow down your interests, buy taking notice to what you are searching for and therefore show you adds that they hope will interest you. For example, I recently bought a pair of shoes from an online shoe store, and for days afterwards I was noticing that advertisements for women's shoes continuously appeared on the sides of Facebook, and other websites I was on. They were even similar websites, with similar looking shoes on them, they caught my eye, and I actually did look at a few of the sites that came up. The internet is narrowing down our interests and figuring out what kind of person you are by recognizing the websites you visit. Shopping online has caused my computer to give me adds for mostly clothing stores. However someone who is into video games or electronics may get a lot of adds for those. This is becoming known as part of our "electronic footprint" its going beyond what we put on Facebook and Twitter, now the internet is recognizing the sites we go on beyond just social media. These days most people have their own laptops, but I'm sure some families still use desktop computers, the problem arises when the whole family had different interests and the children are getting adds for whatever mom and dad are doing on the computer. This could potentially become a privacy concern. The internet is marking its users as children, teenagers, young adults, parents, senior citizens, and so on. They are marketing toys to the users who are on websites playing games, and clothes to teenagers shopping online.

This is potentially a very large advancement in marketing, but do you think this is crossing the line between simply marketing a product and an invasion of privacy? How do you think this new form of marketing could affect the way people use the internet?
