Advertising mediums have had their ups and downs, some have stuck around, while others have slowly drifted away. There are the new mediums that have popped up, only time will tell with those.
Advertising used to rely solely on television and print mediums. They were the two main forms of advertising and most advertising dollars spent were spent between them. Over the years, the list has expanded.
Advertisers now realize the importance of spreading out their budget over multiple platforms. Participating in trade shows, and creating custom trade show displays has become a big part of many company's strategy.
Mobile has also taken over the scene. Many companies are designing their website to be mobile compatible and participating in online advertising platforms such as Adwords, MSN Ad Center, Facebook and LinkedIn.
Although print and television are still around as advertising platforms, the amount of money being spent there has drastically decreased. Search engine optimization and online marketing is pulling funding away from those into developing an online presence rather than commercials and magazine ads.
Many people can argue that television and magazine ads are still one of the best ways to get your point across, but they will probably not try to argue against the importance of an online presence. Many shoppers have gone online. Whether they are using the internet to actually buy, or just research, companies need their products in front of these consumers.
Will television and magazine ads completely go away? No one knows. Only time will tell. Will mobile be where advertising dollars completely shift to? Again, only time will tell. Right now it seems that a good balance between is the way to go.
