Sales of books, in both print and digital formats, are struggling around the world, despite the efforts to promote reading on World Book Day. However there is one area that's bucking the trend: Audio books.
World Book Day is promoted a worldwide celebration of books intended to encourage reading, but revenue from book publishing is falling worldwide.
Statistics from Euromonitor released in 2015 show that turnover from book publishing has experienced sharp declines in recent years. Between 2011 and 2014, revenue fell from $165 billion to $145 billion. The harshest decline was 2011-12, when the global book market contracted 7.4 percent.
