Is there a reason why DSL isn't available in area? I'm stuck here in dialup hell, someone please get me out?

I have been searching in vain for DSL service for many months. Ive tried services such as Verizon and Earthlink, yet for some ungodly reason it isnt available in my area. My current internet provider is AOL and even they can't offer me anythingold dial-up. I have no idea why its like this. I'm hurting here, to download a five minute song it takes between 20-30 minutes. I live in the suburbs of Pittsburgh, its not like I';m in boonies or anything. Its looks as if cable internet and dial-up is the only two options. I'm in need of divine intervention.....
