In addition to its original MSN Dial-up service, Microsoft has used the 'MSN' brand name for a wide variety of products and services over the years, notably Hotmail (which is now Outlook.com), Messenger (which was once synonymous with 'MSN' in Internet slang and has now been replaced by Skype), and its search engine (which is now Bing), as well as several other rebranded and discontinued services.
