Starbucks introduces new drinks and services to reverse declining U.S. sales.

Starbucks aims to boost lagging US sales with new products like cold foam protein drinks and coconut water-based beverages. Despite a 4% revenue rise to $9.5 billion in the fiscal third quarter, same-store sales fell 2%, marking six consecutive quarters of decline. The company is also rolling out the "Green Apron Service" model to improve service and operations, and plans to introduce improved baked goods and a new dark roast coffee.
