Pop-up advertising itself is a good, cheap and extremely productive marketing solution1. It permits the seller to link the buyers’ interest to their site, and the customers to get the dynamic updates on the goods they want to buy. When the consumer will get a pop-up notification that the TV set he desires to purchase is offered at the online shop he/she saw previously with a 15% price cut, one will definitely use this possibility and buy it. Considering the very low cost for the popups and their targeting, such an advertising tool is a favorite thing among the advertising teams of huge online retailers.

# Copyright (c) 1993-2006 Microsoft Corp.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#

# lines or following the machine name denoted by a ‘#’ symbol.
