Cheddar, an online business news channel that targets millennials, is set to implement traditional digital broadcasting methods in addition to their streaming services currently used. The network will air programming on digital UHF stations in five markets that reach more than 4 million homes. Cheddar is renting the broadcast spectrum from DTV America, which owns the licenses. Dunkin’ Donuts, which already advertises on Cheddar, will distribute antennas at events in those markets.
