Vonage, Dollar, and Phoenix Online University top the list of the top 100 May online advertisers who spent a whopping $245 Million for online advertising. I’m not clear how this compares to the online ad spend total as this leaves out the mom and pops who buy a lot of adwords on Google, Yahoo, and MSN.

You don’t need a degree from Phoenix Online U to say “Wow, that’s real money dudes!”.
