From this PEW study
The study did find that local TV news is rarely the primary source for information on things like housing, jobs, taxes or community events, or, put another way, has built its business on a handful of topics with wide appeal. It warned that, given that that local TV dominates in categories — breaking news, weather — where timeliness is a factor, mobile platforms could be a threat to that dominance.
The study found the ‘net to be “especially powerful” for info that required input from citizens-restaurants or education. It is also a top source of news for most topics among younger demos, with mobile devices used to get information by 47%, though still in a supplemental role.
