The Internet
• As compared with other alternative technologies the
Internet offers:
– international connectivity and access to international markets,
– a strong North American market, which in many senses could be
viewed as the domestic market for most Internet retailers,
– full multimedia display facilities, which allow retailers to display
and demonstrate their products, possibly with the use of audio and
video (in some cases, as in the sale of music, for example, such
facilities allow the customer to sample the product),

• Display web pages and interactive forms,and to run programs
such as plug-ins and Java
• Enable navigation between sites by using forward and
backward options and hyperlinks
• Record on the hard disk a copy of sites visited and the pages
downloaded (caching), to enable quicker downloading and
referencing in future.
• Allow useful sites to be bookmarked for later use
</div>
<span class='text_page_counter'>(9)</span><div class='page_container' data-page=9>
The Benefits of Web Browsers

Internet Marketing Mix
<i>• Promotion - includes advertising and creating product </i>
awareness. Information must be presented in a way that will hold
the users' interests.
<i>• One-to-one contact - unlike a real store, the Net does not offer </i>
marketers opportunities of synchronous one-to-one contact with
customers. The Net does, however, allow for asynchronous
contact via e-mail, and this can be used to develop a relationship
with a customer.
