MSN Messenger was an instant messaging program developed by Microsoft that allowed users to communicate in real-time over the internet. Launched in 1999, it enabled users to send text messages, share files, and engage in voice and video calls. The platform became popular for its user-friendly interface and features like emoticons and customizable status messages. In 2013, Microsoft discontinued MSN Messenger and replaced it with Skype, which offered more advanced communication options. Despite its closure, MSN Messenger remains a nostalgic part of internet history for many users who enjoyed connecting with friends and family during its peak years.
