I need information on average results from online banner advertising
in the technology industry (optimally from the software industry, but
general tech will work as well).  I would like the research to be from
the last two years, optimally it would be from 2005.

I am interested in the following data:

What is the average CTR (click-thru rate) for online banner
advertising?  (In my own research I have seen answers anywhere from
.06 - .5%  I would like a final answer)

What is the average or a generally accepted CPC (cost per click) for
online banner advertising in the technology industry?  (I am
interested in an actual number)

What is the average CPM (cost per thousand impressions) for online
banner advertising in the technology industry?

I am looking for hard data, and I would appreciate all sources to be cited.

Thank you in advance!
