SEASON PREMIERE: This is the Season 11 premiere of this incredibly successful CBS sitcom, easily the most visible and popular program continuing the multi-camera, filmed-before-an-audience format instituted so long ago by another CBS sitcom, I Love Lucy. Tonight’s program picks up where last season’s comedy cliffhanger ended: with Jim Parson’s Sheldon on one knee, proposing to Amy (Mayim Bialik).
