With three generations of Kobo e-readers under its belt and widely available, along with the Kobobooks.com e-book store and partnership with the (faltering) Borders book chain, Kobo has become increasingly visible in only two years and now claims to control roughly 10 percent of the US e-book market. Its latest e-reader, the eReader Touch, has received largely positive reviews while Kobo's e-reading apps have topped the iTunes Store and are the default e-book platform on tablets from Samsung and RIM.


Kobo produces several e-readers with e-paper screens. Kobo's e-readers use Wi-Fi to sync a user's book collection and bookmarks with Kobo's cloud service, which can also be accessed from Kobo e-reading apps for Windows and OS X computers and Android, iOS, BlackBerry, and Windows Phone smartphones.

There are thousands of eBooks sold on Kobo store, most of which are DRM protected, exactly the reason that people couldn't share their purchased Kobo eBooks with others. The book file formats supported by Kobo eReader devices include EPUB, EPUB3 (Note: Kobo Original and Kobo Wi Fi does not support EPUB3), PDF, and MOBI.
