67 Per Cent (67 What Per Cent?)

The power of the "headline" never ceases to amaze.

The following headline was seen on FT.com (Financial Times) website.

   Google revenues surge 67 per cent

Question: 67 what per cent? Revenues are typically in units of dollars, but 67 dollars per cent doesn't make sense.

The posting for the headline started as follows.

   "Google's net revenues surged 67 per cent in the 
    final quarter of last year, ahead of estimates."

If we assume the "per cent" is suppose to be "percent," it prompts the question: 67 percent when compared to what? Net revenues could be up 67% compared to the previous quarter or they could be up 67% compared to the same quarter a year ago or they could be up 67% from estimates.
