Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Kobo launched as a Canadian indie startup spun off from Indigo Books, positioned as the affordable, open-format alternative to the Kindle. With EPUB support, sideloading capability, and the lowest-priced 6-inch e-reader at $149, the product had minimal enshittification vectors. Minor lock-in existed from standard ebook DRM, and governance was simple startup structure.
Rakuten's $315 million acquisition brought financial stability and global distribution but introduced corporate governance complexity. The botched Japan launch with hidden negative reviews and the ebook price-fixing controversy (2010-2017 agency model) raised regulatory and transparency concerns. Kobo's proprietary KEPUB DRM format became the default for store purchases, deepening lock-in beyond standard Adobe DRM.
Kobo matured into a full platform with the Kobo Plus subscription service (launched 2017 in Netherlands), OverDrive library integration under common Rakuten ownership, and Shelfie acquisition. The Rakuten write-down of $70 million in 2015 confirmed Kobo was a strategic investment rather than a profit-extraction vehicle. Lock-in increased as library accumulation grew alongside DRM restrictions, though sideloading and open EPUB remained available.
Kobo introduced full-page Kobo Plus advertisements on paid e-reader devices via a firmware update, breaking its previous ad-free positioning. The sale of OverDrive to KKR in 2020 began degrading library integration. Kobo Plus expanded aggressively, launching in the US in 2023 and additional markets. The Walmart partnership faded and was discontinued in 2024. Dark patterns emerged with subscription cancellation friction and on-device advertising.
Kobo maintains a solid core reading experience but shows accumulating signs of early enshittification. A firmware update bricked older devices in 2025, OverDrive integration degraded after the KKR sale, hardware and subscription prices increased twice, the desktop app was discontinued without notice, and Adobe DRM support information was actively hidden. Lock-in through DRM and account-tied libraries remains the primary concern at score 5.
Alternatives
Free app from OverDrive that lets you borrow ebooks and audiobooks from your public library at no cost. Supports most e-reader devices including Kobo hardware. Easy switch for anyone with a library card — the only cost is waiting for popular titles. Best for occasional readers who don't need to own books.
The dominant e-reader ecosystem with a larger device lineup, deeper catalog, and broader format support than Kobo. Moderate switch — purchasing Kindle hardware is straightforward, but ebooks are locked to Amazon's DRM and can't be transferred to non-Kindle devices. Kobo's open EPUB format is actually more portable, so switching to Kindle is a step down in format freedom.

Indigo Spins Off Shortcovers as Kobo Inc.
Indigo Books & Music spun off its Shortcovers digital reading service into an independent company named Kobo, securing $16 million in funding. Indigo retained 58% ownership, with minority stakes from Borders, Cheung Kong Holdings, and REDgroup Retail. The name 'Kobo' is an anagram of 'book.'
First Kobo E-Reader Launches at $149
Kobo released its first dedicated e-reader, a 6-inch E Ink device priced at $149, the lowest-cost 6-inch e-reader available at the time. The device supported open EPUB format and came preloaded with 100 public domain books, establishing Kobo's identity as an affordable, format-open alternative to the Kindle.
Kobo Adopts Agency Model Pricing for Ebooks
Kobo moved to agency pricing terms for ebooks from major publishers, joining a broader industry shift triggered by Apple's iBookstore launch. Under the agency model, publishers set retail prices and retailers receive a fixed 30% cut, replacing the wholesale model where retailers set consumer prices. The adoption later became central to the Canadian Competition Bureau's price-fixing investigation covering 2010-2017.
Rakuten Acquires Kobo for $315 Million
Japanese e-commerce giant Rakuten announced acquisition of Kobo for $315 million in cash from Indigo Books & Music and other shareholders. The deal closed on January 11, 2012. Kobo had been burning through millions monthly and the acquisition provided financial stability while giving Rakuten entry into the global ebook market.
Kobo Writing Life Self-Publishing Platform Launches
Kobo launched Writing Life, a free self-publishing platform offering authors 70% royalties on ebooks priced $2.99-$9.99 and 45% outside that range, comparable to Amazon KDP. Authors retained the option to enable or disable DRM on their titles. The platform attracted over 30,000 authors from 157 countries within two years.
Rakuten Hides Negative Reviews After Botched Japan Launch
Rakuten launched the Kobo Touch in Japan on July 19, 2012, but the device suffered widespread activation failures, buggy desktop software, and a Japanese ebook catalog of only 18,894 titles versus the 30,000 advertised. After receiving 483 one-star reviews, Rakuten disabled product reviews for the first time in its history. CEO Hiroshi Mikitani called bad feedback 'misinformation,' drawing significant criticism.
Kobo Store Bug Produces Random Ebook Prices
A bug in Kobo's online store caused ebooks to display random prices, remaining unresolved for over a month. Some titles showed wildly inflated or discounted prices. The incident raised concerns about Kobo's quality assurance practices in its storefront software.
Kobo Removes All Self-Published Titles After Pornography Scandal
After the Daily Mail exposed that Kobo and WHSmith were selling self-published ebooks featuring rape, incest, and bestiality alongside children's books, Kobo removed all 7,883 self-published titles from its WHSmith-linked catalog. The sweeping removal affected thousands of innocent authors, with many losing access to their sales channels for weeks. WHSmith shut down its entire website in response.
Canadian Ebook Price-Fixing Consent Agreement Filed
The Canadian Competition Bureau filed consent agreements with four major ebook publishers (Hachette, HarperCollins, Macmillan, Simon & Schuster) addressing anti-competitive pricing practices under the agency model from 2010 onward. Kobo challenged the agreement, arguing it unfairly altered contracts underlying its business model, but the Federal Court of Appeal ultimately dismissed its challenge.
Rakuten Acquires OverDrive for $410 Million
Rakuten acquired OverDrive, the dominant digital content provider to libraries serving 30,000+ libraries worldwide, for $410 million from private equity firm Insight Venture Partners. The acquisition deepened Kobo's integration with library lending systems and gave Rakuten control of both the ebook retail and library lending sides of the market.
Rakuten Takes $70 Million Write-Down on Kobo
Rakuten recorded a goodwill impairment charge of 7.8 billion yen (~$68-70 million) against Kobo, approximately a fifth of the $315 million acquisition price. Rakuten cited a 'slower start to the rise of the global ebook industry than originally expected.' The write-down was part of a broader 38.1 billion yen impairment across multiple Rakuten subsidiaries.
Kobo Acquires Shelfie Print-to-Digital Platform
Rakuten Kobo acquired Shelfie, a service that let users photograph their physical bookshelves to receive free or discounted ebook versions. The deal included technology assets, IP, and the Shelfie team specializing in big data and machine learning for book discovery. Shelfie had ceased operations in January 2017 before the acquisition.
Kobo Plus Subscription Service Launches in Netherlands
Kobo launched its Kobo Plus unlimited ebook subscription service in the Netherlands and Belgium, competing with Amazon's Kindle Unlimited. The service initially offered access to a limited catalog for a monthly fee, marking Kobo's entry into recurring subscription revenue alongside its traditional per-title sales model.
Kobo Launches Walmart Ebooks Partnership in US
Rakuten Kobo and Walmart officially launched 'Walmart eBooks by Rakuten Kobo,' offering 6 million ebooks and audiobooks through a co-branded app and Kobo e-readers in over 1,000 US Walmart stores. At the time, Kindle held 83.6% US e-reader market share versus Kobo's 13.4%.
Rakuten Sells OverDrive to KKR Private Equity
KKR completed its acquisition of OverDrive from Rakuten, ending the five-year period when Rakuten owned both Kobo and the dominant library ebook lending platform. Rakuten recognized approximately $365.6 million in profit from the sale. The divestiture later led to degradation of Kobo's library integration as OverDrive under KKR deprioritized Kobo compatibility.
Kobo Introduces Sideload Mode for Account-Free Use
Kobo firmware update 4.31.19086 added a Sideloaded Mode allowing users to operate their e-readers without signing into a Kobo account or connecting to WiFi. Previously, Kobo devices required internet registration during initial setup. The feature enabled fully offline use for readers who only sideload DRM-free content.
Full-Page Kobo Plus Ads Appear on E-Reader Devices
After a firmware update in late July 2022, Kobo e-readers began displaying full-page popup advertisements promoting Kobo Plus subscriptions when waking from sleep mode. The ads appeared on multiple models including the Nia, Clara HD, Sage, Libra 2, and H2O across Canada, Australia, Belgium, Italy, Netherlands, and Portugal. Hundreds of users complained on MobileRead and Reddit, noting Kobo had previously marketed its devices as ad-free.
Kobo Plus Subscription Launches in United States
Kobo Plus became available in the US at $7.99/month for Read or Listen, or $9.99/month for both combined, directly competing with Amazon's Kindle Unlimited. The US launch expanded Kobo Plus availability to its largest potential market, offering access to over 1.5 million ebooks and 150,000 audiobooks.
Kobo Launches First Color E-Readers
Kobo released its first color E Ink devices: the Kobo Libra Colour (7-inch, stylus-compatible) and Kobo Clara Colour (6-inch). Both featured Kaleido 3 color displays, were waterproof (IPX8), and made from recycled ocean-bound plastics. The launch represented a significant hardware innovation maintaining Kobo's competitive position against Amazon's color Kindle lineup.
CDN $15.175M Ebook Price-Fixing Settlement Distributed
National class action settlements totaling CDN $15.175 million were distributed to Canadian consumers who purchased eligible ebooks between April 2010 and March 2017. The settlement covered anti-competitive pricing practices by major publishers and Apple, with Kobo having unsuccessfully challenged the underlying consent agreements.
Authors Charged Undisclosed Fees on Kobo Royalty Payments
Self-published authors reported that Kobo's payment partner Western Union was charging small fees on royalty disbursements without prior disclosure, reducing authors' actual earnings below the stated royalty rates. After complaints surfaced on author forums, Kobo acknowledged the issue and refunded the fees, but the incident highlighted limited transparency in Kobo's payment infrastructure for its 55,000+ Writing Life authors.
Walmart-Kobo Partnership Ends, Walmart Accounts Discontinued
Kobo officially ended its partnership with Walmart, discontinuing the co-branded ebook apps and removing the Walmart sign-in option from Kobo e-readers. Users who had purchased ebooks through their Walmart accounts were required to migrate to standard Kobo accounts by October 31, 2024, or risk losing access to their purchased content.
Kobo Raises E-Reader Hardware Prices by $10
Kobo increased prices on its Clara BW ($139.99), Clara Colour ($159.99), and Libra Colour ($229.99) by $10 each across the US, Canada, UK, and other markets. This was the second $10 price increase in two years, following a similar hike in 2023. The increases widened the gap between Kobo and Amazon's more competitively priced Kindle lineup.
Kobo Found Hiding Adobe DRM Support Information
Reporting revealed that Kobo was actively concealing the fact that its e-readers support Adobe DRM, burying this information in old help articles while its FAQ falsely stated third-party books must be 'free of DRM.' This suppression of interoperability information increased practical lock-in by preventing users from easily loading DRM-protected library ebooks from non-Kobo sources.
Kobo Plus Subscription Price Increased 20%
Kobo Plus Read subscription price increased from $9.99 to $11.99/month, a 20% hike. The Read & Listen bundle also increased to $12.99-$13.99/month. Kobo cited the need to 'continue to innovate on the reading experience and grow the selection of available books.' The increase followed the 2023 expansion to the US market.
OverDrive Removes Multiple Library Card Support from Kobo
OverDrive, now owned by KKR, removed the ability for Kobo e-reader users to link multiple library cards, limiting them to a single card at a time. The feature had been enabled when Rakuten owned both companies. Kobo blamed OverDrive and OverDrive blamed Kobo, but the root cause was OverDrive's deprecation of legacy infrastructure in favor of the Libby app brand.
Firmware Update Bricks Older Kobo E-Readers
Kobo firmware update v4.38.23429, pushed to replace Mozilla Pocket with Instapaper integration, caused older e-readers from 2011-2019 to enter infinite boot loops, rendering them unusable. The only fix was a full manual factory reset that erased all sideloaded books and settings. Kobo pulled the update and offered free device replacements even for out-of-warranty units.
Enshittification Concerns Emerge About Kobo's Direction
The eBook Reader Blog published an analysis asking whether Kobo had reached 'the enshittification stage,' citing declining software update quality and frequency, two rounds of $10 hardware price increases, the desktop app discontinuation without notice, device-bricking firmware updates, refund policy tightening, and Kobo Plus ads on paid devices. The article noted 'more negative changes than positive changes' over the preceding two years.
Rakuten Group Eliminates 100 Positions in Restructuring
Rakuten Group eliminated 100 positions across its global operations as part of a restructuring initiative, primarily affecting corporate functions, marketing, and technology roles. While the layoffs spanned multiple departments, Kobo's core operations were not specifically targeted, and the subsidiary maintained full staffing in customer-facing and engineering roles.
