Listen to Adtech Conference Presentations for Free
Adtech is a digital marketing conference held all over the country and all of their speakers presentations are available for download on their site for free. I wish more conferences did this. TED is one of the premier conferences in the country and that costs thousands to attend, but they give all of their content away for free on their website. On the Adtech site you can listen to presentations by the CMO of Kodak, panel discussions by experts in digital marketing, and a hundred other presentations.
