Yes, I found the same information yesterday. The problem isn't the overall number, although about.com doesn't support their numbers with anything other than the reputation of their website.

I've met (and had business dealings with) the business principals of about.com in the late 90s...if the 75million number is bullshit, it wouldn't suprise me in the slightest.
However, the point made here is not whether the 75 million is true, but whether the bullshit numbers that make up the 75 million, as presented by Dan are ...because at least one of the numbers presented, (13 million for GH) is already certified 15x platinum here in the US.
Conservatively speaking, there's at least 45 million sales here in the US, as certified by the RIAA. The other 30 million so-called sales, aren't as easily tabulated, but I'm quite certain that Frontiers sales don't make up the same sales as escape and gh combined. That's assinine.
It might behoove people here to support their statements with some good old fact and be able to cite where they got it. This sorta bullshit regarding made up numbers is like someone quoting statistics in politics....it's usually completely pulled out of ones ass to prove their assertion, which is really just an opinion they want to shove across the table.
