Online Advertising

§  Search: second largest reach; high advertising value
§  Commerce: high reach; not conducive to advertising
§  Entertainment: large reach; strong targetability
§  Community: emphasize being a part of something; good for specific advertising
§  Communications: not good for branding; low targetability
§  News/weather/sports: poor targetability
§  Games: good for very specific types of advertising
