In some respects, cable TV/Internet businesses ought to work like 
utilities. It takes a lot of capital to build the infrastructure, but 
once it's in place customers send in monthly checks like clockwork. It's
 never quite worked out that way, however, as seemingly never-ending 
capital demands have prevented many of these companies from turning into
 steady dividend-generating machines. 
Virgin Media (Nasdaq:
VMED)
 is an interesting case study. On one hand, the company's high-quality 
network is valuable and the company has consistently delivered on 
ARPU. On the other hand, the company faces competition from conventional competitors such as 
British Sky (Nasdaq:
BSYBY) and 
BT Group (NYSE:
BT), as well as content rivals such as 
Netflix (Nasdaq:
NFLX), 
Amazon (Nasdaq:
AMZN), 
Google (Nasdaq:
GOOG) and 
Apple (Nasdaq:
AAPL). Worse still, the company's huge debt load crushes a 
discounted cash flow model - leading to the question of how much debt should matter to investors.
