According to the study done by the Internet Innovation Alliance:
Using broadband saves you $7700 per year. For a $490 (on average) investment you can save almost $8000. Here are the top 10 ways. Entertainment and Newspapers have a lot to worry about as they are at the top of the cost savings potential, with newspapers completely losing all revenue with broadband. No wonder the papers want to close off access to their intellectual property.
And of course paying bills is a no brainer (this saves money not just for consumers but bill presenters too).
Here's the list of cost cutting in order of actual money saved. I wonder what the cost savings is for Entertainment if you factor in illegal download of movies and music too? Smart consumer mobile and online app vendors would be wise in figuring out how to penetrate the lower categories and help consumer save even more money in areas like housing, food and apparel.
