Hall, author of The Online Advertising Playbook, said: ”Meteor is doing for social media what Google did for search: enabling monetisation at scale… For the last few years I’ve been watching the growth of social media and wondering who’s going to make all this activity economically meaningful.”

He will work alongside Meteor co-founder and CEO Ben Straley to help lead the firm through its next growth stage and execute new revenue plans for 2009.

Straley said: “Taddy joining our team marks a major milestone in the development of our business. His impressive background as an advertisising, marketing, branding and sales authority is exactly what we were looking for.”
