We kicked off the Think2010 blog series 14 weeks ago with the idea of helping you prepare for the coming year by devoting one post each week to big-picture, forward-looking themes supported by actionable tips. Over the course of the series we've covered topics such as relevance, speed, experimentation and innovation. We've discussed the multiple roles that search can play, how to use data to better connect with customers, and the importance of staying focused on the fundamentals. We've also deliberately infused the series with perspectives from thought leaders both inside and outside of Google in order to give you a range of insights on the changing face of marketing. You can find a more in-depth version of this same conversation taking place on our Fast.Forward. YouTube channel.

Here's what a diverse group of industry leaders have to say about the new marketing landscape and the vast opportunity that they believe lies ahead for 2010:
