VKontakte (VK) is a popular Russian social networking service launched in 2006, often referred to as the 'Russian Facebook,' with over 239 million accounts predominantly held by Russian speakers. The platform emphasizes community building, allowing users to interact through messages, group creation, and media sharing, while also serving as an effective marketing tool for businesses to engage with their audience. VK distinguishes itself from Facebook by focusing on entertaining content and emotional discussions among users.
