PRWeb is a penny-stock / SEO favorite because essentially you can pay PRWeb $499 and your story goes onto Yahoo Finance, Bloomberg, WSJ, etc in their "Press Releases" sections (which in some cases appear directly next to the stock information).
Brands like the SF Chronicle have entire sections dedicated to PRWeb where anybody can borrow the SFGate credibility / wrapper and publish just about anything they like, like say a slip & fall attorney:
So yah, we all know that editorial standards are slipping but that was just a face plant by reporting agencies.
In the late 90s, companies would add ridiculous statements like "company X manages large scale industrial controls in the same vein as GE (NYSE:GE) , HP (NYSE:HPQ) and IBM (NYSE:IBM)" to scam yahoo and other pubs into linking their PR From the popular stock pages. It was very lame.
I don't see how they'd even make their money back on the $500 press release at those prices, but whatever.
Someone needs to kill OTC/pink sheets. The NYSE/Nasdaq is close-enough to a scam, god knows that the non-listed guys aren't helping.
