There are a lot of other companies out there trying to get your attention to win your business, but few have developed as big of a customer base as Comcast has done. This is not just pure luck or anything either, as they have established this by delivering quality content and trying to keep customers happy. Like any company, they have had their setbacks, but their commitment has not withered and their spread has continued to accelerate. Over at http://www.cable-tv.com/comcast/ you can learn about some of the differences between this company and the competition, especially their biggest competitor DirecTV.
The reason DirecTV is such a big competitor is that nearly any home can sign up for DirecTV as long as they have a clear sight from their roof towards the DTV satellite up in the sky. Most homes qualify for this, while Comcast must have a solid network laid out in an area before they can even consider the option of serving customers there. This requires a lot of investment, which is why most of the other top cable companies avoid going into areas where big competition has a solid grip over the potential customers.
Since DirecTV can be everywhere, they constantly look for ways to one up all of the cable companies and potentially steal away customers. For starters they flat out have the best customer service in the whole market, which has led to many awards and a lot of praise from past customers. Another great feature exclusive to DirecTV is the NFL Sunday Ticket package which is the only way to watch every single NFL game. Many games are broadcast on national television, but that does not do much good if your favorite team or player happens to be skipped on a given week. This ultimately makes it an easy decision for many people, but others do not care so the quest to find the best continues.
