== History ==
On January 15, 2005, the two owners of eHow, [[Jack Herrick]] and [[Josh Hannah]], started wikiHow—a collaborative writing project to build the world's largest how-to manual. While eHow already contained instructions on how to do thousands of things, wikiHow allowed a community of volunteer contributors to build something even bigger and better. On April 28, 2006, eHow was sold to [[Demand Media]] and wikiHow was launched as an independent site on its own domain.<ref>cite web| last = Herrick| first = Jack| title = History of eHow and wikiHow| publisher = wikiHow|month=September | year=2006| url =| accessdate =October 26, 2006</ref>

wikiHow reached 50,000 articles on January 27, 2009.<ref>cite web |url= |title=wikiHow Statistics |accessdate=January 22, 2009</ref> On March 11, 2011, the number of how to articles hit 100,000. 112 users are administrators, and three are bureaucrats.<ref name=whstats>cite web |url= |title=wikiHow Statistics |accessdate=March 13, 2011</ref>

As of November 2011, there have been over 7,224,751 page edits, there are over 127,479 articles, 387,490 users, and 1,099,137,196 page views.<ref name=whstats/> As of August 2012, there are over 143,000 articles.

== Content and article format ==
[[File:WomenonWikiHow2-WM2012.JPG|thumb|200px|Workshop on women on wikiHow at [[Wikimania]] 2012.]]
wikiHow is a [[wiki]], which is a website that anyone can edit. wikiHow operates on open source software and an open content licensing model allowing free use and community ownership of the content.

Any visitor to wikiHow can create a new page and write about how to do something. Articles posted to wikiHow follow a standard format consisting of a summary, followed by ingredients (if any), steps to complete the activity, along with tips, warnings, required items, links to related how-to articles, and a section for sources & citations. Pictures may be added to the articles to illustrate important points or concepts. Once the page is submitted, other visitors can edit or improve the page. Anonymous contributors and the wikiHow user community work together to improve the quality of information provided on the site, fix or remove incorrect instructions, and revert vandalism.

=== Deletion policy ===
wikiHow's deletion policy<ref>How to Understand What wikiHow Is Not wikiHow</ref> prohibits articles on topics that are [[Advertising|advertisements]], [[Spam (electronic)|spam]], inaccurate, [[joke]]s, [[Toilet humour|potty humor]], [[Sarcasm|sarcastic]], [[Human sexuality|sexually]] charged, [[Hatred|hate]]/[[Racism|racist]]-based, mean-spirited, [[Impossibility|impossible]] instructions, social instructions impossible for an individual to accomplish, universally illegal, [[copyright]] violations, below [[character (arts)|character]] article standards, focused on [[Recreational drug use|recreational drugs]], [[Freedom of thought|political opinion]] promoting or criticizing a particular political party/candidate/official, [[vanity]] pages, or extremely [[Risk|dangerous]] and [[Recklessness (psychology)|reckless]].<ref>cite web |url= |title=wikiHow Deletion Policy|publisher = wikiHow|accessdate=March 8, 2007 </ref>

== Business model ==
The site's initial start-up costs were to some extent financed from Herrick's sale of eHow. It is now funded from advertising on its pages, on the grounds that "…tasteful advertising is the most unobtrusive way to fund our operations."<ref name=aboutwikihow /> It does not seek contributions, asserting that solicitations are annoying, and it is run as a "hybrid organization" – a "for-profit company focused on creating a global public good in accordance with our mission".<ref>cite web|url= |title=Hybrid Organization |publisher=wikiHow |date=October 5, 2010 |accessdate=January 27, 2012</ref>

=== Opt-out ads ===

wikiHow is one of only a handful of major websites to allow readers control over whether advertising appears alongside content. Readers can block ads for 24 hours by clicking the "hide ads" button.<ref name=hide>wikiHow:Why Hide Ads – wikiHow.</ref> Those who are registered and logged in do not see ads,<ref name="hide"/><ref>cite news |title=Turning the Ads Off |url= |date=January 30, 2009 |work=Digits ( |work=The Wall Street Journal | first=Marisa | last=Taylor</ref> unless it is an external video provider.<ref>[Curation Tips|wikiHow:Video Curation#Video Curation Tips]</ref>

== Criticisms ==
Prior to adopting the Creative Commons license, wikiHow had been criticized for initial content policies that sought to make a profit from volunteer contributors.<ref>cite web |url= |title=wikiHow: Thanks, But No Thanks|date=June 3, 2005|author=Ernest Miller|accessdate=January 25, 2008</ref> The site has also been criticized about the reliability of articles written by non-experts, such as "[[Wikihow:Stop-Cutting-Yourself|How to stop cutting yourself]]", or the relevance of articles written about such obscure subjects as "[[Wikihow:Taste-Dark-Chocolate|How to taste dark chocolate]]".<ref>cite web |url= |title=How to do absolutely everything |date=October 16, 2006 |author=Addelman, Rebecca | |accessdate=March 2, 2007</ref>

As wikiHow continued to grow, it began to attract more media attention. Columnist [[Mark Patinkin]] from the [[The Providence Journal|Providence Journal]] wrote an article about wikiHow in late 2009, commenting that he found many interesting articles on a variety of different subjects.<ref name="Mark Patinkin">cite web |url=|title=Columnist Mark Patinkin: ‘Wiki’ site tells me the how, but not the why |date=December 6, 2009 |author=Mark Patinkin| |accessdate=December 1, 2009</ref> In the same article, he said [regarding some of the article topics]:

<blockquote>Some were too dicey, like [[wikihow:Mount-a-Unicycle|How to Mount a Unicycle]]. Others had daunting titles: [[wikihow:Change-a-Partition-Size-Using-Easeus-Partition-Manager|How to Change a Partition Size Using Easeus Partition Manager]]. Some were too long, like [[wikihow:Be-Organized|How to Be Organized]]. Others too obscure: [[wikihow:Care-for-Sea-Monkeys|How to Care for Sea Monkeys]]. Some too hard: How to [[Wikihow:Play-a-Glissando-on-a-Wind-Instrument|Play a Glissando on a Wind Instrument]]. Others I didn’t want to know about, like [[Wikihow:Cook-a-Snake|How to Cook a Snake]]. Some simply grossed me out: [[Wikihow:Cure-a-Cat-of-Constipation|How to Cure a Cat of Constipation]]. Others demoralized me: [[Wikihow:Check-out-a-Library-Book|How to Check out a Library Book]]. Do people no longer know?<ref name="Mark Patinkin"/>
