We never run ads on Wikipedia. Wikipedia is funded by more than a million donors, who give an average donation of less than 30 dollars. We run fundraising appeals, usually at the end of the year. If you’re seeing advertisements for a for-profit industry (see screenshot below for an example) or anything but our fundraiser, then your web browser has likely been infected with malware.

Malware installed on your computer may inject advertising into a page on popular websites, such as this Wikipedia article. This is an example that we've seen in the wild. Note the tiny text "ads not by this site" immediately below the ad, which may or may not appear next to these types of injected advertisements.

One example that we have seen installs itself as a browser extension. The extension is called “I want this” and installs itself in Google Chrome. To remove it:

• Open the options menu via the “pipe-wrench” icon on the top right, and choose Settings.
• Open the Extensions panel and there is the list of extensions installed.
• Remove an Extension by clicking the Remove button next to an item.

There is likely other similar malware that injects ads into Chrome, Firefox, Internet Explorer and other popular browsers. If you see examples that you can document, please point them out in the comments.

Ads injected in this manner may be confined to some sites, even just to Wikipedia, or they may show up on all sites you visit. Browsing through a secure (HTTPS) connection (which you can automate using the HTTPS everywhere extension) may cause the ads to disappear, but will not fix the underlying problem.

Disabling browser add-ins is a good starting point to determine the source of these types of ads. This does not necessarily fix the source of the problem either, as malware may make deep changes to your operating system. If you’re comfortable attempting a malware scan and removal yourself, there are various spyware/malware removal tools. Popular and well-reviewed solutions include Ad-Aware and Malwarebytes. But be aware that these types of tools may also bundle software, or leave your computer in an unusable state.

If in doubt, have your computer evaluated for malware by a competent and qualified computer repair center.

There is one other reason you might be seeing advertisements: Your Internet provider may be injecting them into web pages. This is most likely the case with Internet cafes or “free” wireless connections. This New York Times blog post by Brian Chen gives an example.

But rest assured: you won’t be seeing legitimate advertisements on Wikipedia.

We’re here to distribute the sum of human knowledge to everyone on the planet — ad-free, forever.

I’m delighted to report that the Wikimedia Foundation can ring in the New Year with the close of our seventh annual fundraiser, having exceeded our goal of $16 million. More than half a million people pitched in an average of around $22 each to support Wikipedia and its sister projects, in our shortest (and most successful) fundraiser to date.

Our community of volunteers is deeply honored that, in only 50 days, 500,000 people from 140 countries came together to support the only non-profit, user supported top-10 website in the world.  In addition to this humbling support for the Wikimedia Foundation, our chapters around the world have raised millions of dollars from hundreds of thousands of donors of their own.

We want to thank every one of our donors for making this year a success, and on behalf of the fundraising team, I personally wish to thank the one-thousand community members who helped us create and test messages, who wrote appeals, and translated banners and letters into over 80 languages.

In 15 days, Wikipedia will turn 10 years old. Since the beginning, Wikipedia’s community of readers and editors have remained dedicated to keeping the site ad-free, and free for use for its 400 million monthly visitors.  This year’s success demonstrates a continued commitment to those principles.

With the close of our annual fundraiser, we are transitioning into the contribution phase of the campaign. We will be running banners for the next few days to thank everyone who came together in the spirit of creating and “effectively disseminating the sum of human knowledge available for all.”  We will also begin to celebrate Wikipedia’s tenth birthday, with banner ads encouraging readers to join us in a local celebration.

We want to invite every one of the readers of Wikipedia and its sister sites to make their  first edit, or upload their first photograph, and join our community of volunteer contributors to continue the growth of Wikipedia for the next 10 years.

Thank you again, and happy New Year! Here’s to 2011, and to the next 10 years!

Regards,

Philippe Beaudette
Head of Reader Relations

Today, I’m pleased to announce the launch of our 2010 annual fundraising drive, which we are referring to as a ”contribution campaign”. This year marks a major milestone for Wikipedia.  Ten years of revolutionizing access to knowledge.  Ten years of our joint commitment to deliver the sum of human knowledge to every human being on the planet.  For free.

Wikipedia and its sister sites champion a mission of effectively disseminating knowledge, free for use, free of copyright, and free of external advertising. Since its founding in 2001, the site has grown to 17 million articles in over 270 languages, and for many of those languages, Wikipedia is the only encyclopedia ever written. Wikipedia, and all the Wikimedia projects, are always there when we need them; for students, educators, professionals and curious minds worldwide, these projects are simply the most convenient and readily accessible sources of information.

This year’s fundraising goal is an ambitious one – $16 million over two months. Wikimedia sites are the 5^th most visited web properties worldwide (visited by about 400 million people each month), and Wikimedia is the only non-profit organization in the top 10. Since 2007 our readership has doubled, with this past September seeing our highest traffic yet.  With this incredible feat comes an enormous duty: to maintain the infrastructure necessary to keep these sites free, stable, and running smoothly, while also continually improving the systems and architecture behind them.

For more information about where your donations go, see this year’s annual plan.

Since the beginning, our fundraising model has been based on the support of our community of readers and editors – we have received more than 500,000 donations in the lifetime of the Foundation, averaging about $33 each.  Will you join us today by making a donation to financially underwrite Wikipedia and its sister sites?

We have worked with almost a thousand community volunteers to develop this year’s fundraiser as a community driven contribution campaign. These exceptional volunteers have helped to develop messaging, design banners, write appeals, and conduct tests of our ideas.

Since August we have been testing these messages and tweaking our campaign to reflect the data and feedback from our community. Due to the introduction of new technology, we now have the ability to target particular banners and donation pages based upon geographic location, and to optimize the pages donors see.

In addition to new technology, we’re introducing a new perspective;  this year’s contribution campaign is designed to invite not only financial contributions, but to also encourage people to contribute their expertise and knowledge to the projects. We want readers to make their first edit, upload their first photograph to Wikimedia Commons, write their first article, and through this, to become more deeply affiliated with the projects.

For updates throughout the fundraiser continue to check our blog, and follow us on identi.ca and Twitter (as @Wikipedia, or the community-run contribution handle @WikiContribute).  After you’ve made a contribution, please tell the world using the hashtag #keepitfree!

This year marks a significant milestone for us, so I hope you will join me – and the diverse community of volunteers that make up the Wikimedia projects – in celebrating and supporting the mission that has brought us all together.

Stay curious!
