In response to Erica Murray

I think that with the internet being such an integrated part of most peoples lives now a days using social networking sites as marketing tools makes a lot of sense. How many people can you think of off hand that are either on Facebook or twitter and how many of those people use or visit that site everyday? With that much traffic it makes a lot of sense for companies to advertise on Facebook or twitter. If I was a company looking to get customers I'd be sure to try and post something on a site that see's something like a million visits a day. With that in mind does it make sense for companies to eventually phase out older methods of advertising and focus more on internet users?
