In addition to running a blog that is part of an existing activity(such as a political campaign, retail business, or newspaper), blogs can become a business in themselves if they can generate financial support through fees or advertising. Jake Dobkins writes about New York City on the blog site Gothamist. Instead of drawing a salary from a newspaper as a food and entertainment reporter, he blogs about the latest in New York nightlife. Advertising revenue has been sufficient to support Dobkins and the site's cofounder, Jen Chung Now with a staff of bloggers, editors, and ad salespeople, these entrepreneurs are expanding into other cities. Michael Arrington began blogging in 2005 about new online business startups. Again, instead of writing a column for a business magazine, he decided to put his research and reporting talents into his own business, which today is operating as TechCrunch, a successful advertising-supported Web site.
