Zedo

Zedo (trademark styled as ZEDO) is a privately held company founded in 1999 by Roy de Souza, which provides several online advertising products and services to Internet publishers, advertisers, and agencies.[1] The company works with publishers who sell space on their web pages to online advertisers. Zedo's servers send advertisements to users' browsers.[2] Zedo uses an HTTP cookie to track users' browsing history resulting in targeted pop-up ad and pop-under ads. The cookie is often flagged by spyware and adware removal programs.[3] In a 2013 case study written by Amazon, Amazon described ZEDO as a company that "develops innovative technology solutions to help publishers sell and deliver Internet ads".[4]

History

Zedo began in 1999. The company headquarters is located in the North Beach district of San Francisco, California. Zedo's development center is in India.[5] In 2001, it expanded by offering the ad-serving technology to large websites.

By 2004, the use of filters to limit pop-ups and pop-unders increased. Zedo began using intromercials—advertisements served before the requested content—as an alternate method.[6]

Zedo has also experimented with creating its own social networking sites. In 2006, it launched a social networking site where users get shopping advice from friends who own products called Zebo.com.[7]

In 2011, Zedo started to work with newspaper publishers.[8]

Criticism

Zedo uses HTTP cookies to track users' browsing and advertisement viewing history.[9] A writer for The Independent called pop-unders from Zedo and other providers "annoying" while also describing the advertisements' windows as a "seemingly endless barrage".[1] Technologist Danny Sullivan has stated that Zedo carries misleading "junk" ads linking to fake news sites.[10]

Zedo offers an option to opt out of targeted advertisements[11] and says that it has an anti-spyware policy.[12]

gollark: This makes sense as a display thing, but how do you run it *backward*?
gollark: I tried playing a 10Hz sine wave just now and I can't hear it.
gollark: The position of the pen clearly can't be being directly mapped to voltage on a speaker or something, because the frequency would be waaaaay too low to hear.
gollark: What property of the waveforms it's generating varies as you change X/Y?
gollark: I'm aware it's converting it into waveforms somehow. That's just very vague.
