Socialization networks have evolved from landline phones to mobile phones to VoIP and Skype. Landline phones had issues with mobility and reliability but were secure, while mobile phones enabled constant connectivity but at the cost of privacy, health, and family time. VoIP provided low-cost international calls over the internet but with quality and reliability issues. Skype became popular for free video and voice calls between users along with additional features, but requires an internet connection and computer. Socialization networks will continue advancing to better connect people.
