McDonald's says it will start offering all-day breakfast nationwide starting October 6th. The fast-food chain had been testing the idea in limited markets since March as it tries to improve slumping sales. 

Customers have been pushing the Golden Arches for years to sell breakfast items beyond the 10:30 a.m. cutoff.   The change is the latest under CEO Steve Easterbrook who took over March 1st.
