Is my understanding of all of this correct? Please tell me what I have wrong. Also please inform me of anything further regarding what I’m talking about. Advertising agencies have to use media companies. They need them, because a media company is essentially the owner of some form of medium- which is the vehicle for the advertising agency’s client’s advert. Now, take for example a media company that publishes a newspaper. We will call it ABC. So am I right to say that ABC owns this paper? ABC has different departments in their organisation. One part is the editor. We will call him John. John is in charge of deciding what things are written about in the paper. That is, he decides what news articles go in there, what adverts go in there, and what advertorials go in there. Now another department within ABC is the journalists, who are the people who write the news articles, about anything they wish. Another department is the publishing team, who actually print the newspaper. Another department is the team who try and find clients to advertise in the herald. And another department is booking the adds and scheduling the ads, whatever that means. So am I right to say the media companies are a big part of advertising? Advertisers have nowhere to advertise without them. MAIN QUESTION: Do media companies have an advertising team of their own? That is, do they create the ads for their clients (some business) or does an advertising agency make an ad for a company and then that agency goes to the media company, whether it be a magazine, a radio station, or a tv channel. Do you know what I found? To answer your “main question” (I answered the rest of it when you posted basically this exact same question earlier): News-based media companies sell advertising space in the form of commercial air time and ad specs in the newspaper. Companies submit their own 30-second (usually) commercials for TV. All the media company does is negotiate when and where to place them. Newspapers sell print and Web advertising. At most papers, the ad space is sold for a specific size (i. E. “two columns wide, 5″ tall" and the company that purchased the ad space will submit their own pre-designed ad to fit the ad spec. However, the newspaper’s ad staff might also employ ad designers. In this case, the company would purchase a set amount of ad space and tell their account manager at the paper EXACTLY what they wanted the ad to say and to look like. A business staff member would design the ad to the specs requested and the company that bought the ad would have final say on the ad before it ran (i. E. If they saw the ad and didn’t like it, it wouldn’t run). This is usually the case in smaller newspapers or college newspapers, which deal with less “glossy” advertisers and smaller companies that would be less likely to have an in-house ad staff to design their own ads. This is a paid service offered by the paper’s business staff and has nothing to do with editorial content. By the time a company can afford to advertise in a NY Times sort of paper, they’re going to be submitting their own house ads. Now, if you’re asking about advertising agencies, that’s a different thing altogether. Ad agencies are ad agencies, they’re not newspapers or TV stations or any other news-based media. They work with (usually larger) companies to determine content, typography, test runs, audience approval and campaigns for advertising. They do not work for a news-based company. The business staffs at newspapers and TV stations negotiate for size, cost, duration and placement of ads, and in some cases design them to spec, and that’s it. They don’t determine the content or do focus groups or anything like that. It’s a business transaction and that’s it.
