Through this development, the medium of radio became the dominant marketing initiative for manufacturers, which led to the innovation/invention of television as the predominant choice of commercial marketing in the mid-20th century. The theoretical process of the Four Ps of Marketing became the dominant form of marketing analysis, which allowed a more dynamic and comprehensive managerial tone to be established in the 1950s and 1960s. These dynamic market-based strategies enabled the expansion of technology and management as the predominant means by which to evaluate marketing developments in “customer orientation” and “relationship orientation” in the 1980s and early 1990s. The decline of TV as a primary marketing medium has been defined by the rise of “social/mobile” marketing, which has increased with the use of the Internet/World Wide Web” as a commercial outlet for advertising and promoting products in 21 th century. . These are the major historical developments in marketing in the context of marketing initiatives, strategies, processes and trends in advertising and management from the 19th century to the 19th century.
