'Empire' scores big ratings for Fox. But can it soar while other TV musicals flail?

"Empire," Fox's new drama starring Terrence Howard as a hip-hop mogul and Taraji P. Henson as his ex-wife and competitor, is looking like a potential triumph for the network: About 10 million people tuned in the premiere on Wednesday night. According to Entertainment Weekly, that figure ties "How to Get Away With Murder" as the most-watched freshman show debut of the season.
