An advertorial is an advertisement in the form of editorial content. The term "advertorial" is a blend (see portmanteau) of the words "advertisement" and "editorial." Merriam-Webster dates the origin of the word to 1946.
In printed publications, the advertisement is usually written in the form of an objective article and designed to look like a legitimate and independent news story. In television, the advertisement is similar to a short infomercial presentation of products or services. These can either be in the form of a television commercial or as a segment on a talk show or variety show. In radio, these can take the form of a radio commercial or a discussion between the announcer and representative. The concept of advertorial is linked to native advertising; however, whether the two terms are synonymous is a point of discussion. 
Advertorials differ from traditional advertisements in that they are designed to look like the articles that appear in the publication. Most publications will not accept advertisements that look exactly like stories from the newspaper or magazine they are appearing in. The differences may be subtle, and disclaimers—such as the word "advertisement"—may or may not appear. Sometimes terms describing the advertorial such as a "special promotional feature" or "special advertising section" are used. The tone of the advertorials is usually closer to that of a press release than of an objective news story.
Advertorials can also be printed and presented as an entire newspaper section, inserted the same way within a newspaper as store fliers, comics sections, and other non-editorial content. These sections are usually printed on a smaller type of broadsheet and different newsprint than the actual paper. Many newspapers and magazines will assign staff writers or freelancers to write advertorials, usually without a byline credit. A major difference between regular editorial and advertorial is that clients usually have content approval of advertorials, a luxury usually not provided with regular editorial.
A related practice is the creation of material that looks like traditional media (for instance, a newspaper or magazine) but is actually created by a company to market its products. One familiar example is airline in-flight magazines, which may feature reports about travel destinations to which the airline flies.
In 1996, Parkway Publishing began publishing advertorials for advertisers. Parkway began enlisting clients and created PRPros to function as PR via advertorials with great success. The cottage industry is now widely used and considered very successful. Sheldon Schorr, the president of Parkway, was a leader in the crafting of advertorials and placed hundreds a year in scores of periodicals, especially magazines, utilizing quotes, brand references and trade enhancement, "meant to compliment a company or persons' brand passively and more affordably than any other form of editorial content with much greater success than a press release". Historically, advertorials were less frowned upon and newspapers would even "show how magazine advertising is serving the public".
Daytime programs featuring light talk designed to draw in mainly a female audience, often use advertorial segments which feature presentations of products, services, and packages by businesses. A representative of a business will have a discussion with a regular host, along with perhaps making a special offer for viewers.
In Australia, daytime programs featuring light talk and advertorials have been in television schedules since the late 1960s. One of the first was Good Morning Melbourne starring Roy Hampson and Annette Allison which began in 1967 followed by Good Morning Sydney in 1978, hosted by Maureen Duvall. They were followed by a national program which began in 1988 on Network Ten called Good Morning Australia with Bert Newton. This success of that show prompted the Nine Network to produce similar shows like In Sydney Today and In Melbourne Today, later merged into Ernie and Denise. Since 2002, Kerri-Anne Kennerley has hosted Mornings with Kerri-Anne, later shortened to Kerri-Anne. The Seven Network followed suit with a show starring Denise Drysdale called Denise before the debut of The Morning Show in 2007. Network Ten had 9am with David & Kim from 2006 which was replaced by The Circle in 2010.
These programs feature a traditional daytime show format of light talk, health, beauty, fashion and recipe segments along with advertorial segments scattered throughout the show. The advertorials are usually hosted by regular advertorial hosts who interact with business representatives. The main hosts of the show usually do not interact with the advertorial hosts or the business representatives. Advertorials are regulated under the Commercial Television Industry Code of Practice, which has been registered by the Australian Broadcasting Authority.
Locally produced daytime television rose in the mid-2000s as local television stations (especially those with the NBC and Fox networks, where NBC gave up the most programming time) saw network time on weekday mornings after 9am returned to local control and saw new national talk shows either fail or not attract the right demographic to a timeslot. Beginning with Daytime on Media General station WFLA-TV in Tampa, Florida in the early 2000s, a new format featuring the structure of a traditional locally-produced daytime show with the usual format of light talk, health features, beauty tips and recipe segments which was popular up to the early 1990s (when expansion of newscasts became a much less expensive, more dependable form of revenue) came into use. Some of these shows, such as WKBW-TV's AM Buffalo in Buffalo, New York, seamlessly made the transition from a traditional local talk show to a paid program with little notice.
This type of program usually features light talk designed to draw in mainly a female audience, and then presentation of products, services, and packages by local businesses; for example a basement waterproofing system might be discussed by the representative of a company in that business with the hosts, along with perhaps a special offer for viewers.
On radio, advertorials can feature discussions between an announcer or a DJ and the representative of a business. The discussion may feature testimonials from customers or a personal endorsement from the announcer. The products featured can range from mobile phone/cable/satellite providers, insurance, financing, auto servicing, travel agencies, and upcoming concerts or music releases.
The Cash for comment affair was an Australian scandal that broke in 1999, concerning paid advertising in radio that was presented to the audience in such a way as to sound like editorial commentary.
In the UK, the Advertising Standards Authority requires advertorials to be clearly marked as such. In one case, the Scottish newspaper The Herald published a feature titled "Professional Brief" that had been submitted by Glasgow-based French Duncan Chartered Accountants. According to a complaint, it did not clearly indicate that it was a paid advertisement. The newspaper argued that, because it was a "sponsored column" and it was indicated that the opinions expressed were those of the author, it did not have to refer to it as an advertisement. The ASA responded that, because payment was given in exchange for the publication of the columns and because the content was provided by the marketers rather than the newspaper, they considered the columns advertisements and required that they indicate as much.
For U.S. magazines mailed at the publication rate, the Postal Service has regulations as to how to mark editorial and advertising. Domestic Mail Manual states that under 18 USC 1734, "if a valuable consideration is paid, accepted, or promised for the publication of any editorial or other reading matter in a Periodicals publication, that matter must be plainly marked 'advertisement' by the publisher. When a single item of paid editorial or other reading matter occupies more than one page, it need only be marked 'advertisement' on the first page. The word “advertisement” may be included in a statement that explains why the material is marked 'advertisement.' Such a statement must be prominent on the first page of the material and the word 'advertisement' in the statement must be in bold or italicized print or otherwise emphasized so that it can be plainly seen. Editors or publishers who print such matter without plainly marking it 'advertisement' are subject to a fine of not more than $500."
