A closed platform, walled garden, or closed ecosystem [1] [2] is a software system wherein the carrier or service provider has control over applications, content, and/or media, and restricts convenient access to non-approved applicants or content. This is in contrast to an open platform, wherein consumers generally have unrestricted access to applications and content.
For example, in telecommunications, the services and applications accessible on a cell phone on any given wireless device were formerly tightly controlled by the mobile operators. The operators limited the applications and developers that were available on users' home portals and home pages.[ citation needed ] Thus, a service provider might restrict user access to users whose account exhausted the pre-paid money on their account. This has long been a central issue constraining the telecommunications sector, as developers face huge hurdles in making their applications available to end-users.[ citation needed ]
In a more extreme example, the regulated 1970s American telephone system, Bell, owned all the hardware (including all phones) and had indirect control over the information sent through their infrastructure. It was an open government-sanctioned natural monopoly regulated by the Communications Act of 1934. However, in the landmark case Hush-A-Phone v. United States , Bell unsuccessfully sued a company producing plastic telephone attachments.
More generally, a walled garden can refer to a closed or exclusive set of information services provided for users. Similar to a real walled garden, a user is unable to escape this closed environment except through the designated entry/exit points or if the walls are removed. [3]
A 2008 Harvard Business School working paper, entitled "Opening Platforms: How, When and Why?", differentiated a platform's openness/closedness by four aspects and gave example platforms: [4]
Aspect of closedness/openness of a platform [4] | Linux | Windows | macOS | Apple iOS |
---|---|---|---|---|
Demand-side use (end-user) | open | open | open | open |
Supply-side user (application developer) | open | open | open | closed |
Platform provider (hardware/operating system (OS) bundle) | open | open | closed | closed |
Platform sponsor (design & intellectual property (IP) rights owner) | open | closed | closed | closed |
Some examples of walled gardens include:
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops, tablets usually run mobile operating systems, alongside smartphones.
An e-reader, also called an e-book reader or e-book device, is a mobile electronic device that is designed primarily for the purpose of reading digital e-books and periodicals.
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance, though its most widely used version is primarily developed by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.
Amazon Kindle is a series of e-readers designed and marketed by Amazon. Amazon Kindle devices enable users to browse, buy, download, and read e-books, newspapers, magazines and other digital media via wireless networking to the Kindle Store. The hardware platform, which Amazon subsidiary Lab126 developed, began as a single device in 2007. Currently, it comprises a range of devices, including e-readers with E Ink electronic paper displays and Kindle applications on all major computing platforms. All Kindle devices integrate with Windows and macOS file systems and Kindle Store content and, as of March 2018, the store had over six million e-books available in the United States.
OverDrive Media Console was a proprietary, freeware application developed by OverDrive, Inc. for use with its digital distribution services for libraries, schools, and retailers. The application enables users to access audiobooks, eBooks, periodicals, and videos borrowed from libraries and schools—or purchased from booksellers—on devices running Android, BlackBerry, iOS (iPad/iPhone/iPod), and Windows, including Mac and Windows desktop and laptop computers.
Calibre is a cross-platform free and open-source suite of e-book software. Calibre supports organizing existing e-books into virtual libraries, displaying, editing, creating and converting e-books, as well as syncing e-books with a variety of e-readers. Editing books is supported for EPUB and AZW3 formats. Books in other formats like MOBI must first be converted to those formats, if they are to be edited.
Rooting is the process by which users of Android devices can attain privileged control over various subsystems of the device, usually smartphones. Because Android is based on a modified version of the Linux kernel, rooting an Android device gives similar access to administrative (superuser) permissions as on Linux or any other Unix-like operating system such as FreeBSD or macOS.
UltraViolet was a cloud-based digital rights locker for films and television programs that allowed consumers to store proofs-of-purchase of licensed content in an account to enable playback on different devices using multiple applications from several different streaming services. UltraViolet also allowed users to share access to their library with up to five additional people. UltraViolet was deployed by the Digital Entertainment Content Ecosystem (DECE), an alliance of 85 companies that includes film studios, retailers, consumer electronics manufacturers, cable television companies, internet service providers (ISPs), internet hosting vendors, and other internet systems and security vendors, with the notable exceptions of Walt Disney Studios, Google, Amazon and Apple.
The Nook Color is a tablet computer/e-reader that was marketed by Barnes & Noble. A 7-inch (18 cm) tablet with multitouch touchscreen input, it is the first device in the Nook line to feature a full-color screen. The device is designed for viewing of books, newspapers, magazines, and children's picture books. A limited number of the children's books available for the Nook Color include interactive animations and the option to have a professional voice actor read the story. It was announced on 26 October 2010 and shipped on 16 November 2010. Nook Color became available at the introductory price of US$249.

The Barnes & Noble Nook is a brand of e-readers developed by American book retailer Barnes & Noble, based on the Android platform. The original device was announced in the U.S. in October 2009, and was released the next month. The original Nook had a six-inch E-paper display and a separate, smaller color touchscreen that serves as the primary input device and was capable of Wi-Fi and AT&T 3G wireless connectivity. The original Nook was followed in November 2010 by a color LCD device called the Nook Color, in June 2011 by the Nook Simple Touch, and in November 2011 and February 2012 by the Nook Tablet. On April 30, 2012, Barnes & Noble entered into a partnership with Microsoft that spun off the Nook and college businesses into a subsidiary. On August 28, 2012, Barnes and Noble announced partnerships with retailers in the UK, which began offering the Nook digital products in October 2012. In December 2014, B&N purchased Microsoft's Nook shares, ending the partnership.
The Amazon Fire, formerly called the Kindle Fire, is a line of tablet computers developed by Amazon. Built with Quanta Computer, the Kindle Fire was first released in November 2011, featuring a color 7-inch multi-touch display with IPS technology and running on Fire OS, an Android-based operating system.

In later generations, the Fire tablet is also able to convert into a Smart speaker turning on the "Show Mode" options, which the primary interaction will be by voice command through Alexa.
A mobile application or app is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device.
The Nook Tablet is a tablet e-reader/media player that was produced and marketed by Barnes & Noble. It followed the Nook Color and was intended to compete with both e-book readers and tablet computers.
