If slow and steady is the best way to win the race then Google is eventually going to dominate the ebook market. Google Play books is now live in France with reportedly thousands of ebooks in French as well as over 600 thousand ebooks from international publishers, including titles by Antonin Varenne, Marc Levy, Eric-Emmanuel Schmitt, Christine Lewicki, P.D.James and John Grisham.
Google's promising that you can read the ebooks via the iOS, Android, and Chrome apps, but I'm still awaiting confirmation that they are available in France. If the apps aren't up yet then French readers can still head to Google Play Books and start browsing and buying books. And of course you can always find the Google Play books app on sites like Freeware Lovers, where it is a free download.
This makes a total of 5 European countries with access to the Google eBookstore (Germany, France, Italy, Spain, UK). If you add in Canada, Australia, and the US, the total population covered by the Google eBookstore is still rather tiny when compared to the markets served by Amazon, Kobo, or even iBooks.
