The scroll wheel on a mouse has been invented multiple times by different people unaware of the others' work.

Other scrolling controls on a mouse, and the use of a wheel for scrolling both precede the combination of wheel and mouse. The earliest known example of the former is the ''Mighty Mouse'' prototype developed jointly by [[Nippon Telegraph and Telephone|NTT]], Japan and [[ETH Zürich]], Switzerland (Kunio Ōno, Ken'ichi Fukaya and Jürg Nievergelt) in 1985. It had a thumb-operated combined [[Analog signal|analog]] [[Mouse button|button]]/[[Switch#Toggle switch|toggle switch]] on the side for smooth scrolling.<ref name=bux>{{citation | first = Bill | last = Buxton | author-link = Bill Buxton | url = https://www.billbuxton.com/inputManuscript.html | chapter-url = http://www.billbuxton.com/input02.Devices.pdf | title = Human Input to Computer Systems: Theories, Techniques and Technology | chapter = Chapter 2: An Illustrated Tour | accessdate = December 8, 2018}}</ref>

At the [[SIGCHI|ACM SIGCHI]] conference in 1989, Gina Danielle Venolia <!-- current name --> from [[Apple Inc.|Apple]] presented a mouse prototype with a horizontal thumb-wheel for scrolling, or for navigating inwards and outwards: [[Zooming user interface|zooming]] or along the third axis in [[Three-dimensional space|3D space]].<ref name=bux/> In her patent application from 1992 there are two vertical wheels: left and right of the button(s).<ref name="venoliapatent">{{cite patent | patent-number = 5313230A | country-code = US | title = Three degree of freedom graphic object controller | inventor-first = Daniel S. | inventor-last = Venolia | inventor2-first = Shinpei | inventor2-last = Ishikawa | publication-date = 1992-07-24 | issue-date = 1994-05-17}}</ref>

In 1995, the [[Taiwan]]ese company [[KYE Systems]] released the first commercial mouse with scroll wheel. It was named ''Genius EasyScroll'' and was also available as ''[[Mouse Systems]] ProAgio''.<ref name="Coding_Horror_Genius_EasyScroll"/><ref>[https://www.gearrate.com/en/mouse/history/ gearrate.com – History of Computer Mouse (1964 ~ 2020)]</ref><ref>[http://www.funtrivia.com/en/subtopics/Quiet-As-a-Mouse-258375.html funtrivia.com – Quiet As a Mouse – Fun Facts, Questions, Answers, Information] {{webarchive|url=https://web.archive.org/web/20130612105011/http://www.funtrivia.com/en/subtopics/Quiet-As-a-Mouse-258375.html |date=2013-06-12 }}</ref><ref name="zmhseg">{{cite web |url=http://itotd.com/articles/330/the-evolution-of-scrolling/ |title=The Evolution of Scrolling: Reinventing the wheel |author=Joe Kissell |publisher=Interesting Thing of the Day |date=2004-10-07 |accessdate=2010-02-12}}</ref>

The scroll wheel was popularized by the [[Microsoft]] [[IntelliMouse]] in 1996 along with support for the mouse wheel in [[Microsoft Office 97]]. It had been based on ideas developed by [[Eric Michelman]] since 1993 with input from Chris Graham.<ref name="Coding_Horror_Genius_EasyScroll">[http://www.codinghorror.com/blog/archives/000865.html Coding Horror: Meet The Inventor of the Mouse Wheel]</ref><ref name="Michelman_Wheel">[http://www.ericmic.com/history%20of%20the%20scroll%20wheel.htm The History of the Scroll Wheel]</ref>

Scroll wheels can also be found on [[Personal digital assistant|PDA]]s and mobiles phones such as early [[Sony]] models, [[BlackBerry]] devices and [[Nokia 7110]], which usually have the function of navigating through menus.<ref>{{cite book|url=https://books.google.com/books?id=ODkmn4EYPxgC&pg=PT45|title=Designing for Small Screens|last1=Zwick|first1=Carola|author1-link=Carola Zwick|author2=Studio 7.5|last3=Schmitz|first3=Burkhard|last4=Kühl|first4=Kerstin|publisher=[[AVA Publishing]]|date=2005|access-date=2022-03-02|pages=51–52|isbn=2-940373-07-8}}</ref><ref>{{cite book|url=https://books.google.com/books?id=pk6iDwAAQBAJ&pg=PA32|title=Disruptive Space Technologies and Innovations: The Next Chapter|last=Madry|first=Scott|publisher=[[Springer Nature]]|date=2020|access-date=2023-03-02|page=32|isbn=978-3-030-22188-1}}</ref> They have also appeared on [[Computer keyboard|keyboards]], particularly on [[Logitech]] and [[Microsoft]] models, usually located to the left of the [[caps lock]] key.
