Are Trade Shows Dead?

After going to several trade show events in the bay area. I have almost concluded that the era of trade shows is slowing dying off as more and more buyers are no longer going to trade shows. This happened at the RSA event RSA Conference and now the VON show is also having trouble See the article here I think this is normal as people are starting to look online to solve their problems more and realize that they can obtain better information simply by searching online. It also maybe because its cheaper to look online then to actually go to a trade show.
