In a large skillet, melt butter over medium heat. Add onion and garlic; cook for 5 minutes. Gradually stir in wine; add thyme sprigs. Cook until wine is reduced by half, about 2 minutes. Add corn and broth; bring to a boil. Reduce heat and simmer until corn is tender, about minutes. Discard thyme sprigs.
In the container of a blender, pour corn mixture. Secure lid on blender and remove center piece of lid to let steam escape; place a clean towel over opening in lid to avoid splatters. Process until mixture is almost smooth. Strain mixture into same skillet, discarding solids.
Stir in cream, chopped thyme, and Old Bay; bring to a boil. Reduce heat, and simmer until sauce is slightly thickened, about 5 minutes.
