What is extra extra read all about it?

"Extra! Extra! Read all about it" is a classic phrase often used by newspaper street vendors to grab the attention of passersby and promote the latest news story or headline. It originated in the late 19th and early 20th centuries when newspapers were a primary source of information and communication.

The phrase became popular in the United States and United Kingdom, where newspaper vendors would shout it to attract customers and sell more papers. It was often accompanied by the waving of newspapers or the ringing of a bell to further capture attention.

Today, the phrase is used more as a nostalgic nod to the past, evoking a sense of urgency and excitement surrounding breaking news. It is commonly used in movies, television shows, and other forms of media to convey a sense of important or sensational information being revealed.
