The popular children’s board book Peek-a-WHO by Nina Laden has sold more than 1 million copies.
The book has been out for 15 years and sales have increased incrementally every year. Last year, the book sold more than 150,000 copies.
“Word of mouth generated sales from the beginning, and they remained stable for six or eight years,” stated Chronicle Books Editor Victoria Rock. “Then the numbers took a big leap, and I think that had to do with the fact that the Internet and social media came more into play. People began reviewing the book online, and word of mouth travels much faster that way.”
