Input:  Person1:       What's the news on our website ? How effective do you think it is from a marketing standpoint ?  
 Person2:We've been able to survey and track some of the information of our website users through some cookie technology , and it's surprising to see the results .  
 Person1:        What kinds of hits are we getting on our company's website ?  
 Person2:From the numbers , it seems nearly half of the visitors who stumble onto our page pick up the link not from network browsers or search engines , but from our circular insert . That means our consumers are purposefully and actively seeking information about our products and services through the web format . Based on these findings , I am completely convinced the internet is the marketing power of the future !  
 Person1:        You really think that many people turn to the internet to find product information.What about the old standbys of word mouth and print media ?  
 Person2:Well , these mediums are still important ... they aren't a thing of the past ... But I think they might be less important now than in the past . The technology age has arrived !
