Pop-up advertising itself is a good, low-priced and also very successful marketing instrument¹. It allows the seller to link the buyers’ attention to their website, and the customers to receive the dynamic updates on the goods they intend to buy.

# 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.
