In just four months of operation, Amazon.com became a very popular site on the Web, making high marks on several Internet rankings. It generated recognition as the sixth best site on Point Communications' "top ten" list, and was almost immediately placed on Yahoo's "what's cool list" and Netscape's "what's new list." The site opened with a searchable database of over one million titles. Customers could enter search information, prompting the system to sift through the company database and find the desired titles. The program then displayed information about the selection on a customer's computer screen, and gave the customer the option to order the books with a credit card and have the books shipped in a just a few days.
