As technology changes, our society changes. In order to keep up, advertising as evolved too. Advertising started in news papers, posters, and fliers. It relied solely on print ads. Soon radio and TV were invented and advertisement took a huge leap. They were able to create more direct content, but it also became must more expensive. These type of advertisements are still very prevalent but recently advertising has taken a new step.
Print ads are moving more and more to online. Every website it seems has some type of advertising on the page to help fund it. Many of these things can be quite annoying to users, but it enables these serves to continue to be free. Another huge change is phones. Now even apps and games on phones have ads running on top of them. Or products make their own apps or games to promote there product.
Yet another new way of advertising is using social media. Companies make Facebook groups to get the word out and to interact with their audience. I think this is very effective. A company has to know how to adapt to stay in the game.
One new type of advertising that I'm not too fond of is commercials before movies. I really enjoy going to movies, and I like to see trailers of up coming movies. Now however they started showing real commercials before movies and I feel that they just don't belong. Movie going is an experience that should be separate from watching TV. I get annoyed seeing commercials in this format. When you go to a movie I expect movie type previews not soda or army ads.
Overall ads are changing along with everything else. They need to keep up in order to do their job. Advertising is a changing field.
