Last year's DAC'10 attendee numbers were down a dismal 35% compared to the
DAC'09 attendee numbers. The funny thing was the DAC Exec Committee back
then tried to hide that 35% drop by quietly double-counting their attendee
numbers in their end-of-DAC 2010 press release. (I didn't catch that trick;
but my readers did!)
This year the DAC'11 attendee numbers were up 9%; and it appears there's
no tricky double-counting in this year's end-of-DAC 2011 press release.
Full Conference Attendees
2007 : : ########################## 2,648
2008 : : ######################## 2,382
2009 : : #################### 1,962
2010 : : ################ 1,554
2011 : : ################# 1,746 +12%
Exhibit-Only Attendees
2007 : : #################### 2,052
2008 : : ################## 1,842
2009 : : ################################# 3,337
2010 : : ################### 1,890
2011 : : #################### 2,006 +6%
Exhibitors
2007 : : ########################################## 4,204
2008 : : ################################### 3,543
2009 : : ########################### 2,697
2010 : : ######################### 2,557
2011 : : ########################## 2,598 +2%
So to get the total change in DAC *attendees*, the math is easy:
(2,006 + 1,746) / (1,890 + 1,554) = up 8.9% = up 9%
But this year's DAC attendance press release wasn't without controversy:
- This year's end-of-DAC 2011 press release claims a "double digit
increase in all categories". Huh? They're +12%, +6%, +2%.
- This year's end-of-DAC 2011 press release claims "Total exhibit-only
attendees: 2,006 (up 13.5% compared to 2010)" Huh? It was +6%.
- Oops! All of the press releases from DAC 2010 are missing on dac.com!
See http://www.dac.com/dac+archives.aspx ... How did that happen?
Look at 2009 and 2008. All the DAC press releases are there. But none
for 2010 nor 2011. It's a good thing that I keep my own copies! :)
And the really funny thing is how many EDA publications and bloggers just
blindly regurgitated "DAC 2011 Shows Double Digit Increase In Attendance"
from this year's end-of-DAC 2011 press release and parroted that 13.5%
number everywhere without doing even *minimal* fact checking!
Ya gotta love today's new non-thinking lapdog EDA "press".
