Pay to surf (PTS) is a business model that became popular in the late 1990s, prior to the dot-com crash. Essentially, a company uses income from advertising placed on members' screens to pay them for time spent surfing.
A PTS company would provide a small program to be installed on a member's computer. Advertisers' banner ads were then displayed while the member was browsing the web. Since the viewbar tracked websites that the user visited, the PTS company was able to deliver targeted ads for their advertisers.
The company should constantly keep in touch with customers to attract them and to encourage customers to re-purchase.
The company should minimize communication with customers in order to reduce costs.
