What can a TV exec learn from a few months of working at Twitter? That was the question we put to Fred Graver, Twitter's new head of TV, who spoke at the second Ad Age Social Engagement/Social TV Conference.

Mr. Graver, whose career highlights include writing for Letterman, creating "Best Week Ever" for VH1 and, most recently, leading programming and development at Travel Channel, has been at Twitter just shy of 120 days. At the event, held at the Beverly Wilshire Hotel in Los Angeles, he shared first impressions ("the company is incredibly well run"); how he realized Twitter is a technology, not a media, company; his goal for his job (for people to say "the hour I spend with TV and Twitter makes my life better"); and one of his big questions -- whether the data Twitter generates can build a new TV rating.
