We consider two different qualities of broadband access, one that simply means greater access speed to Internet applications and content, and a premium version that also gives access to interactive TV services. Based on a market survey we find that potential consumers of this premium broadband access do not consider basic broadband Internet access as a substitute. The price of basic broadband does not constrain the price that may be charged for the premium broadband that allows for interactive TV services. Copyright Kluwer Academic Publishers 2004
