While much smaller than the US and European book markets, the Singaporean book market still mirrors the genre trends in these countries. Books that are popular in the US and Europe tend to be popular in Singapore, as Penguin Books Singapore's Managing Director Eddy Teo explains. The popular genres today include young adult fiction, self-improvement, and biographies. As the country's economy continues to strengthen and prosper, the government support for literature continues to grow through book industry awards and special programs that encourage local writing and reading. With a total population of around five million people the revenue potential from books sales within the country itself is small, so most local authors find success by exporting their titles and making them available for sale in larger markets.
