PechaKucha is a presentation style in which 20 slides are shown for 20 seconds each (6 minutes and 40 seconds in total). The format, which keeps presentations concise and fast-paced, powers multiple-speaker events called PechaKucha Nights (PKNs). PechaKucha Night was devised in February 2003[4][5] by Astrid Klein and Mark Dytham of Tokyo's Klein-Dytham Architecture (KDa), as a way to attract people to SuperDeluxe, their experimental event space in Roppongi, and to allow young designers to meet, show their work, and exchange ideas.A typical PechaKucha Night (PKN) includes 8 to 14 presentations. In each presentation 20 slides are shown for 20 seconds each. Organisers in some cities have added their own variations to the format.The audience is usually from the design, architecture, photography, art and creative fields, but also from academia.[10] Most presenters are design professionals showing their creative work, but presenters often speak about such topics as their travels, research projects, student projects, hobbies, collections, or other interests.

Advertising is an audio or visual form of marketing communication that employs an openly sponsored, nonpersonal message to promote or sell a product, service or idea.Sponsors of advertising are often businesses who wish to promote their products or services. Advertising is differentiated from public relations in that an advertiser usually pays for and has control over the message. It is differentiated from personal selling in that the message is nonpersonal, i.e., not directed to a particular individual.Advertising is communicated through various mass media,[2] including old media such as newspapers, magazines, Television, Radio, outdoor advertising or direct mail; or new media such as search results, blogs, websites or text messages. The actual presentation of the message in a medium is referred to as an advertisement or "ad".
