What we do and what typical Ad Agencies do
Long-gone is the era of Madison Avenue men. What is cornerstone to a modern day Ad Agency isnt high profile clients, but the value that an advertising company can provide Clients of all sizes, budgets and unique needs. Our Clients include entrepreneurs, sole proprietors, small businesses, corporations, non-profit organizations and government agencies. We are often contracted by to produce multifaceted media campaigns for all types of industries. While some advertising agencies limit the amount and kind of service they offer. Such agencies usually offer only one or two of the basic marketing services. For example, although some agencies that specialize in "creative" also offer strategic advertising planning service, their basic interest is in the creation of advertising. Similarly, some "media-buying services" offer media planning service but concentrate on media buying, placement, and billing. On the other hand The McKenna Agency has 5 specilized divisions;
Specialist Advertising Services
In addition to the full-service, general-line advertising agencies, there are also agencies that specialize in particular kinds of advertising: recruitment, help-wanted, medical, classified, industrial, financial, direct-response, retail, yellow pages, theatrical/entertainment, investment, travel, and so on. As a general rule our agency does not focus a specific industry.
Interactive services 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. Offering 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. Today, the most successful interactive agencies are defined as companies that provide specialized advertising and marketing services for the digital space.
Lately, pay per click (PPC) and (SEO) search engine optimization firms have been classified by some as 'agencies' because they create media and implement media purchases of text based (or image based, in some instances of search marketing) ads. This relatively young industry has been slow to adopt the term 'agency', however with the creation of ads (either text or image) and media purchases, they do technically qualify as 'advertising agencies'.
Social media agencies specialize in promotion of brands in the various social media platforms like blogs, social networking sites, Q&A sites, discussion forums, microblogs etc. The two key services of social media agencies are:
Healthcare communications agencies specialize in strategic communications and marketing services for the Healthcare and Life Science industries. These agencies distinguish themselves through an understanding of the strict labeling and marketing guidelines mandated by the U.S. Food and Drug Administration (FDA) and industry group guidelines, most notably ADVAMED and PHARMA.
Medical education agencies specialize in creating educational content for the Healthcare and Life Science industries. These agencies typically specialize in one of two areas:
The people who create the actual ads form the core of an advertising agency. Modern advertising agencies usually form their copywriters and art directors into creative teams. Creative teams may be permanent partnerships or formed on a project-by-project basis. The art director and copywriter report to a creative director, usually a creative employee with several years of experience. Although copywriters have the word "write" in their job title, and art directors have the word "art", one does not necessarily write the words and the other draw the pictures; they both generate creative ideas to represent the proposition (the advertisement or campaign's key message). Creative departments frequently work with outside design or production studios to develop and implement their ideas. Creative departments may employ production artists as entry-level positions, as well as for operations and maintenance. The Creative Process forms the most crucial part of the advertising process.
Agencies appoint account executive to liase with the clients. The account executives need to be sufficiently aware of the client's needs and desires that can be instructed to the agency's personnel and should get approval from the clients on the agency's recommendations to the clients. Creativity and marketing acumen are the needed area of the client service people. They work closely with the specialists in each field.
The media services department may not be so well known, but its employees are the people who have contacts with the suppliers of various creative media. For example, they will be able to advise upon and negotiate with printers if an agency is producing flyers for a client. However, when dealing with the major media (broadcast media, outdoor, and the press), this work is usually outsourced to a media agency which can advise on media planning and is normally large enough to negotiate prices down further than a single agency or client can.
Without the production department, the ads created by the copywriter and art director would be nothing more than words and pictures on paper. The production department, in essence, ensures the TV commercial or print ad, etc, gets produced. They are responsible for contracting external vendors (directors and production companies in the case of TV commercials; photographers and design studios in the case of the print advertising or direct mailers). Producers are involved in every aspect of a project, from the initial creative briefing through execution and delivery. In some agencies, senior producers are known as "executive producers" or "content architects".
Marketing is everywhere, but chances are your firms marketing is not. Effective advertising encompass the emergence of digital, computerized, or networked information and communication technologies that have become all present.
Engagement and Interactivity have become the terms for the modern media use options evolving from the rapid dissemination of Internet access points based on the digitalization of the media, and media convergence. In 1984, Rice defined the new media as communication technologies that enable or facilitate user-to-user interactivity and interactivity between user and information.  Such as Internet replaces the "one-to-many" model of traditional mass communication with the possibility of a "many-to-many" web of communication. Any individual with the appropriate technology can now produce his or her online media and include images, text, and sound about whatever he or she chooses.  So the new media with technology convergence shifts the model of mass communication, and radically shapes the ways we interact and communicate with one another. Vin Crosbie described three communications media in “What is new media?”. He saw Interpersonal media as “one to one”, Mass media as “one to many” and, finally New Media as Individuation Media or “many to many”.
When we think of interactivity and its meaning, we assume that it is only prominent in the conversational dynamics of individuals who are face-to-face. This restriction of opinion does not allow us to see its existence in mediated communication forums. Interactivity is present in some programming work, such as video games. It's also viable in the operation of traditional media. Other settings of interactivity include radio and television talk shows, letters to the editor, listener participation in such programs, and computer and technological programming. 
Interactivity can be considered as a central concept in understanding new media, but different media forms possess different degree of interactivity , even some forms of digitized and converged media are not in fact interactive at all. Tony Feldman  considers digital satellite television as an example of a new media technology that uses digital compression to dramatically increase the number of television channels that can be delivered, and which changes the nature of what can be offered through the service, but does not transform the experience of television from the user’s point of view, as it lacks a more fully interactive dimension. It remains the case that interactivity is not an inherent characteristic of all new media technologies, unlike digitization and convergence.
New Media changes continuously due to the fact that it is constantly modified and redefined by the interaction between the creative use of the masses, emerging technology, cultural changes, etc.
