YouTube (Flash video support)

YouTube, a popular video-sharing platform, originally used Adobe Flash technology to stream videos. Flash allowed users to watch videos directly in their web browsers, offering a smooth viewing experience. However, due to concerns over security vulnerabilities and the rise of more efficient technologies like HTML5, Flash support was discontinued in favor of these newer methods. HTML5 provides better performance, security, and compatibility across devices, allowing YouTube to deliver high-quality video streaming without needing additional plugins. While Flash was integral in YouTube's early days, the platform has since evolved to utilize more modern technologies.
