I am hoping to stop paying for cable this year, is it easy to do?
Yes it is , a fact is that internet content is either free or significantly cheaper than the same content provided via cable
What are some services that I can use to watch tv over the internet?
Such services such as Hulu, itunes, netflix, sling, and youtube are all great
I see commercials about Sling, what doe Sling offer?
Not much information on that but as a market trend cord cutters do not pay for subscription television anymore
I hate paying my $100 cable bill...what a waste.  Is there a lot of content on YouTube?
Yes it has great content you should check it out.  Another fact is that in 2008 900,000 americans relied solely on internet for television viewing 
That is crazy, make that 900,001 after today!
I agree with you!  I am one of the 900,000 people now
