Overview

iWiW was a Hungarian social networking service built around real-name identity, personal profiles, and relationship discovery. It began on 14 April 2002 under the name WiW, an abbreviation of “Who Is Who,” before being rebuilt and relaunched as iWiW in October 2005. The service was designed primarily for Hungary and became an important early national social platform before the global dominance of Facebook. Users could create profiles containing personal details such as their place of residence, date of birth, education, employment, interests, and pets. The service’s discovery model emphasized trusted or semi-trusted social connections: members could search for people directly or navigate through the acquaintances of existing contacts. This made the platform useful both as a personal address book and as a way to map social and professional relationships. The 2005 rebuild introduced the iWiW name and several functional changes. These included a multilingual interface, although the service later returned to Hungarian-only operation, profile and classified listings, photo uploading, and a Java-based visualization of users’ connections. The changes helped position iWiW as a broader social-networking environment rather than a simple directory. Its emphasis on identifiable users and local relationships also gave it a distinctive role in Hungarian internet culture. Growth was rapid. iWiW reached one million users in July 2006 and 1.5 million users by December of the same year. By August 2007 it reportedly had 2.6 million registered users using real names. Registered membership reached approximately four million by December 2008, a figure that represented a very large share of Hungary’s internet population at the time. The scale of the service made it a significant national communications platform and an attractive acquisition target. On 28 April 2006, T-Online, the internet business of Magyar Telekom, acquired iWiW from Virgo Systems Informatikai Kft. for almost one billion Hungarian forints, reported at the time as approximately US$4.7 million. The takeover generated user concerns about privacy and the possible commercial use of personal information. These concerns contributed to interest in iWiW clones and other Hungarian social-networking sites, although the platform continued to expand under its new ownership. After the acquisition, the interface was available only in Hungarian. The service continued to add platform capabilities as social networking evolved. Twenty-six applications became available on the site in April 2009, and the number had grown to 65 by the middle of that year. In April 2010, iWiW introduced a login service comparable to Facebook Connect, allowing users to access participating external websites with their iWiW credentials. In July 2010, it expanded into mobile access with applications for iPhone and Android. Despite its early domestic scale, iWiW eventually lost ground as international social networks, particularly Facebook, became more influential in Hungary. Origo Zrt. announced on 15 May 2014 that the service would close permanently. The shutdown took effect on 30 June 2014, ending iWiW’s operation after roughly twelve years. Its history illustrates the rise of locally dominant social platforms, the strategic importance of network effects, and the difficulty of defending a national service against globally scaled competitors.

History

iWiW originated as WiW, short for “Who Is Who,” on 14 April 2002. It was created as a Hungarian social-networking service based on identifiable users and their personal connections. Rather than relying only on anonymous discussion or public broadcasting, the platform encouraged members to describe themselves and connect through real-world acquaintances. Profile fields included residence, birth date, schools, universities, workplaces, interests, and pets. A search function enabled users to locate people, while an acquaintance-of-an-acquaintance model helped them discover wider connections. The service was rebuilt from scratch on 26 October 2005 and relaunched under the name iWiW, generally explained as “International Who Is Who.” The new version added a multilingual interface, listings, photo uploads, and a Java applet that displayed relationships visually. The multilingual feature was later removed, and by July 2006 the site operated in Hungarian only. The redesign marked a transition from an online directory into a more feature-rich social platform. User growth accelerated during 2006. iWiW reached one million users on 18 July and 1.5 million on 18 December. On 28 April 2006, T-Online, the internet division of Magyar Telekom, acquired the service from Virgo Systems Informatikai Kft. for almost one billion Hungarian forints, reported in contemporary accounts as about US$4.7 million. The acquisition gave iWiW the backing of a major telecommunications group but also raised concerns among users about whether their personal data could be sold to telemarketers or used for other commercial purposes. Fears about possible misuse of information contributed to the emergence or increased visibility of iWiW clones and other Hungarian social-networking services. The platform nevertheless continued to grow. By August 2007 it reportedly had 2.6 million registered users using real names. Registered users reached four million by 24 December 2008, a scale that covered almost all Hungarian internet users according to contemporary descriptions. This made iWiW one of the most prominent domestic internet services in Hungary and a central place for maintaining personal and professional contacts. During 2009, iWiW developed an applications ecosystem. Twenty-six applications were made available on 22 April, and the total had reached 65 by the middle of the year. In April 2010, the service launched an authentication feature similar to Facebook Connect, allowing members to log into external websites with their iWiW accounts. In July 2010, iWiW introduced mobile applications for iPhone and Android, reflecting the broader shift from desktop social networking toward mobile access. The service’s later history was shaped by intensifying competition from international networks, especially Facebook. Although iWiW had achieved exceptional local penetration, its domestic focus and dependence on a national user base made it difficult to match the product development, global network effects, and international reach of larger competitors. Origo Zrt. announced on 15 May 2014 that iWiW would close permanently on 30 June. The shutdown ended more than a decade of operation and marked the disappearance of one of Hungary’s defining early social-networking brands.
