Step-by-step explanation:
The publication that described a certain phenomenon as the world's favourite youth culture is not clearly identified within the context provided. However, it is important to note that numerous publications have chronicled the various youth cultures that emerged throughout the 20th century and into the 21st century. For instance, The Beatles and their impact on youth culture during the 1960s were well documented, representing suburban youth culture and its evolution towards rebellion, as highlighted by events like the Woodstock concert in 1969.
Another key aspect of youth culture is the rise of LGBTQ journalism post-1969 Stonewall Riots, with publications such as Gay Sunshine and The Advocate paving the way for a more liberated community. Understanding the world's favourite youth culture is subjective and can be influenced by different eras and social movements, as seen in pop culture, LGBTQ rights, and even in the subcultures within Soviet Russia, as noted by scholars like James von Geldern and Richard Stites.
