One can seldom be placed in a position of responsibility upon first joining this profession. Very often he has to start his career in a junior position and it requires years of work experience before he advances to higher positions. Although there are opportunities for new recruits to advance to supervisory and executive positions, the competition is very keen. Promotion prospects largely depend on individual merits. In a booming economy where competition among various products is intense, advertising activities are indispensable and likely to expand in variety and scope. People joining the industry must therefore acquire new knowledge and keep abreast of the social development.
