With the release of Windows 95 in August 1995, Delrina was now competing directly against Microsoft in the fax/electronic communications marketplace, as Windows 95 included a basic faxing application as an accessory, along with a licensed version of Hilgraeve's HyperTerminal communication package, (which was also used as the basis for Delrina's own WinComm program). While these applications offered only rudimentary fax and online communication services in comparison to the mature Delrina products, Microsoft was perceived as a potentially serious future competitor in the communications market space. The release of the initial version of Microsoft's Internet Explorer in late 1995 as a free product effectively killed off the early emerging market for non-free browsers, creating a market where Delrina's Cyberjack browser could not hope to compete.
