Skype is a communication platform developed in 2003 by Niklas Zennström, Janus Friis, and a team of Estonian developers. It’s name, originating from ‘Sky peer-to-peer,’ highlights its function to connect users globally. Skype allows individuals to communicate via mensagens instantâneas[1], voice chat and video calling, and additionally supports file transfers and conference calls. It also offers a debit-based service for calls to landlines and mobiles. Since its acquisition by Microsoft[2] in 2011, Skype has been integrated with other Microsoft products, providing enhanced features like high-definition video quality and Skype chat integration into Office software. Skype has continued to innovate, introducing features like background blurring in video chats using AI algorithms. Despite its vast capabilities, it does not support emergency calls in all countries.

Definições de termos
1. ↑ mensagens instantâneas. Instant Messaging (IM) is a digital communication method that enables real-time transmission of text-based messages over internet or computer networks. Unlike email, IM facilitates immediate, interactive conversation, often enhanced with emojis, file transfers, voice-over IP, and video chat. IM systems can function independently or as part of a larger social media platform. They have evolved significantly since early systems like Talkomatic and CompuServe CB Simulator, developing into graphical user interfaces with a wide range of features. Today's popular services, including Signal, Telegram, WhatsApp, and Snapchat, offer private and group messaging, advanced security measures such as end-to-end encryption, and integration with social networks. They play a vital role in both personal communication and business environments, facilitating effective real-time communication with conversation records for future reference.
2. ↑ Microsoft ( Microsoft ) A Microsoft é uma empresa tecnológica reconhecida mundialmente, conhecida pelo seu software, hardware e outros serviços digitais. Fundada em 1975 por Bill Gates e Paul Allen, lançou produtos revolucionários como o sistema operativo Windows, o pacote Microsoft 365 e as consolas de jogos Xbox. Sob a liderança do seu atual CEO, Satya Nadella, a Microsoft alargou o seu âmbito de aplicação à computação em nuvem e prosseguiu uma política de aquisições activas, incluindo o GitHub e a Mojang, para melhorar a sua oferta de produtos. Apesar de enfrentar críticas e desafios legais sobre o comportamento de monopólio e questões de usabilidade, a Microsoft manteve um desempenho financeiro sólido, atingindo mesmo uma capitalização de mercado de um bilião de dólares em 2019. Atualmente, continua a inovar e a expandir-se, ocupando uma posição significativa na indústria tecnológica global.

Skype was created by Niklas Zennström, Janus Friis, and four Estonian developers, and first released in August 2003. In September 2005, eBay acquired it for $2.6 billion. In September 2009, Silver Lake, Andreessen Horowitz, and the Canada Pension Plan Investment Board bought 65% of Skype for $1.9 billion from eBay, valuing the business at $2.92 billion. In May 2011, Microsoft bought Skype for $8.5 billion and used it to replace their Windows Live Messenger. As of 2011, most of the development team and 44% of all the division's employees were in Tallinn e Tartu, Estonia.

Skype originally featured a hybrid peer-to-peer e client–server system. It became entirely powered by Microsoft-operated supernodes in May 2012; in 2017, it changed from a peer-to-peer service to a centralized Azure-based service. As of February 2023, it was used by 36 million people each day.
