An advertising agency is a business that specializes in developing and placing advertisements for companies so that their products and services are recognized. Advertising agencies not only develop advertising strategies for companies but can also take control of all branding, sales promotion and marketing activities.
Advertising agencies come in all sizes, everything from one to two person shops to large multinational companies. Also, nowadays you do not need to have a huge advertising agency to land all the large contracts with major clients, it is extremely common for smaller advertising agencies to handle large accounts. Therefore, there are huge opportunities for a start up advertising agency to enter the market and become a success.
It is also common for advertising agencies to specialize in particular industries such as retail, charitable etc. Therefore if you have worked in a particular industry or sector and are thinking of starting your own advertising agency then that specific industry may be a good place to start because you will know the market very well.
The advertising industry at the moment is continuing to grow due to the fact that all companies are always creating new products or services and they require them to be advertised to the public in order to make sales. Thus, there will always be opportunities for new advertising agencies.
