The first few releases of the product were made available in "commercial" and "evaluation" versions; for example, version "1.0" and version "1.0N". The "N" evaluation versions were completely identical to the commercial versions; the letter was there to remind people to pay for the browser once they felt they had tried it long enough and were satisfied with it. This distinction was formally dropped within a year of the initial release, and the full version of the browser continued to be made available for free online, with boxed versions available on floppy disks (and later CDs) in stores along with a period of phone support. During this era, "Internet Starter Kit" books were popular, and usually included a floppy disk or CD containing internet software, and this was a popular means of obtaining Netscape's and other browsers. Email support was initially free and remained so for a year or two until the volume of support requests grew too high.
