Internet Explorer 1.0

Microsoft released, as a part of its bonus package, the Microsoft Plus! Internet Jumpstart Kit (later also known as the Internet Connection Wizard) for Windows 95, which included Internet Explorer 1.0. In the original version of Windows 95, a web browser was not available, as Microsoft underestimated the potential of the rapidly developing Internet.

The source code for Internet Explorer 1.0 was based on the older Spyglass Mosaic browser for which Microsoft purchased license rights. Internet Explorer 1.0 occupied only 1 MB of disk space and its features were considerably limited compared to other browsers at the time.
