What is the landmass called that stretches from Santa Barbara to San Diego and is dominated by the Los Angeles area?

Southern California.

“Southland” and “Inland Empire” although the Inland Empire includes San Bernardino County,

I recall a poster from my youth growing up there last century that called the area from Los Angeles to San Diego:
Losandiegoles

I thought it was called SoCal. Am I wrong?

I have heard it called PCH (Pacific Coast Highway) referring to the whole area.

@YARNLADY – PCH refers to Hwy 1, running all the way up the west coast.

@YARNLADY Yes, but many people ate expanding the meaning to refer to the entire region.
