Interactive Agencies may differentiate themselves by offering a mix of Web Design/Development, Search Engine Marketing, Internet Advertising/Marketing, or E-Business/E-Commerce consulting. Interactive agencies rose to prominence before the traditional advertising agencies fully embraced the Internet.

      A wide range of services, some of the interactive agencies grew very rapidly, although some have downsized just as rapidly due to changing market conditions.

     Commercial photography

       The most successful interactive agencies are defined as companies that provide specialized advertising and marketing services for the digital space. The digital space is defined as any multi-media enabled electronic channel that an advertiser's message can be seen or heard from.Commercial photography is probably best defined as any photography to which money exchanges hands. In this light money could be paid for the subject of the photograph or the photograph itself. Wholesale, retail, and professional uses of photography would fall under this definition.

      Besides the camera, other methods of forming images with light are available. For instance, a photocopy or xerography machine forms permanent images but uses the transfer of static electrical charges rather than photographic film, hence the term electrophotography. Photograms are images produced by the shadows of objects cast on the photographic paper, without the use of a camera. Objects can also be placed directly on the glass of an image scanner to produce digital pictures.
