Thousands of advertisements are produced every year, which never appear on our TV screens and are considered too shocking to be seen. In order to appear on the screen, they must clear various obstacles, from picky clients to obsessive regulatory agencies and restrictive rights issues. "X-level: Advertisements They Can't Display" conducted a special examination of these illegal advertisements for an hour and a half, revealing the most blatant, controversial, and shocking advertisements that have never been seen before. These advertisements break various taboos, from sex, violence, blasphemy, homosexuality, animal abuse, rap for pension recipients, cursing children, suicide toys, and nude athletes, to Kelly riding a wild horse in underwear. Contributors include advertising executives, producers, and reviewers. The program also focuses on the awkward world of Western celebrities in Japanese advertising, as well as the biggest thing that has happened in the advertising industry since television: the emergence of viral campaigns: advertisements that reach the inbox are not subject to the same regulation as television advertisements.
