Another significant trend regarding future of advertising is the growing importance of the niche market using niche or targeted ads. Also brought about by the Internet and the theory of The Long Tail, advertisers will have an increasing ability to reach specific audiences. In the past, the most efficient way to deliver a message was to blanket the largest mass market audience possible. However, usage tracking, customer profiles and the growing popularity of niche content brought about by everything from blogs to social networking sites, provide advertisers with audiences that are smaller but much better defined, leading to ads that are more relevant to viewers and more effective for companies' marketing products. Among others, Comcast Spotlight is one such advertiser employing this method in their video on demand menus. These advertisements are targeted to a specific group and can be viewed by anyone wishing to find out more about a particular business or practice at any time, right from their home. This causes the viewer to become proactive and actually choose what advertisements they want to view.
Google AdSense is an example of niche marketing. Google calculates the primary purpose of a website and adjusts ads accordingly; it uses key words on the page (or even in emails) to find the general ideas of topics disused and places ads that will most likely be clicked on by viewers of the email account or website visitors.
