Internet marketing,
also known as web marketing, online marketing, webvertising, or e-marketing, is referred to as the marketing (generally promotion) of products or services over the Internet.
Internet marketing
is considered to be broad in scope because it not only refers to marketing on the Internet, but also includes marketing done via e-mail and wireless media. Digital customer data and electronic customer relationship management (ECRM) systems are also often grouped together under internet marketing.
Internet marketing ties together the creative and technical aspects of the Internet, including design, development, advertising and sales.
Internet marketing also refers to the placement of media along many different stages of the customer engagement cycle through search engine marketing 
(SEM), search engine optimization (SEO), banner ads on specific websites, email marketing, mobile advertising, and Web 2.0 strategies
Advertising is a form of communication used to encourage or persuade an audience (viewers, readers or listeners. Sometimes a specific group of people.) to continue or take some new action. Most commonly, the desired result is to drive consumer behavior with respect to a commercial offering, although political and ideological advertising is also common. The purpose of advertising may also be to reassure employees or shareholders that a company is viable or successful. Advertising messages are usually paid for by sponsors and viewed via various traditional media; including mass media such as newspaper, magazines, television commercial, radio advertisement, outdoor advertising or direct mail; or new media such as blogs and websites and text messages.
Commercial advertisers often seek to generate increased consumption of their products or services through “branding,” which involves the repetition of an image or product name in an effort to associate certain qualities with the brand in the minds of consumers. Non-commercial advertisers who spend money to advertise items other than a consumer product or service include political parties, interest groups, religious organizations and governmental agencies. Nonprofit organizations may rely on free modes of persuasion, such as a public service announcement (PSA).
Modern advertising developed with the rise of mass production in the late 19th and early 20th centuries.
In 2010, spending on advertising was estimated at $142.5 billion in the United States and $467 billion worldwide
Internationally, the largest (“big four”) advertising conglomerates are Interpublic, Omnicom, Publicis, and WPP
