Qihoo 360 Technology Co. Ltd., or Qihoo 360, (Chinese: ; pinyin: Qíhǔ, pronounced CHEE-hoo in English) is a Chinese internet security company known for its antivirus software (360 Safeguard, 360 Mobile Safe), Web Browser (360 Browsers), and Mobile Application Store (360 Mobile Assistant). It was founded by Zhou Hongyi and Qi Xiangdong in June 2005.[2][3] Qihoo 360 had 496 million users for its Internet Security products and 641 million users for its Mobile Antivirus products as of June 2014.[4]

Business Model[edit]

Qihoo 360 initiated its business operations by selling third-party antivirus software online. Soon afterwards they realized the potential of the freemium business model in the Chinese market and started providing their own antivirus products free of charge. In a short period of time, Qihoo 360's security products gained popularity and market share in China. Their current revenues are generated by leveraging their massive user base through online advertising and services such as online games, remote technical support, and system integration.
