A broadcast designer is a person involved with creating graphic designs and electronic media incorporated in television productions that are used by character generator (CG) operators. A broadcast designer may have a degree in digital media (or a similar degree), or is self-taught in the software needed to create such content. [bolox] CG stands for computer graphics, most broadcast designers studied either graphic design or visual communication - this term is used for those designing motion graphics also for film, industrials, commercials & the web.
Another industry which is reliant on a designer's skill is the television commercial advertising market. Most often, a client will hire an advertising agency which will then hire a group of designers to produce a commercial for their product. The process usually begins with a concept or an idea which the client has or the agency comes up with. It is then further explored in design boards which go up for approval by the client before the process of making it actually begins.
