Tina Brown Takes Her Pitch to Fox Business | Tina Brown appeared on Fox Business today to chat about her new site, the Daily Beast. It turns out that credit for the venture goes to Barry Diller, who, Brown says, was having trouble finding anything worthwhile to read on the Web and brought the idea to Tina because he wanted someone he could trust to tell him what to read every day. Oh, and don't be fooled by the title of the segment, "The Battle of the Blogs," or the lead-in, which suggests she's giving the Huffington Post and the Drudge Report a run for their money. She isn't competing with anyone. "It's not a competitive situation... it's a collegial model."
