Hotmail (officially Microsoft Hotmail, previously Windows Live Hotmail and MSN Hotmail) was a free web-based email service operated by Microsoft as part of Windows Live, which was recently replaced by the newer Outlook.com service by Microsoft. Hotmail was one of the first web-based email services, it was founded by Sabeer Bhatia and Jack Smith and launched in July 1996 as "HoTMaiL". It was acquired by Microsoft in 1997 for an estimated $400 million, and shortly after, it was rebranded as "MSN Hotmail". The current version was released in 2011.
