Another change is coming to MSNBC daytime – Dr. Nancy Snyderman‘s progam, which has aired at NoonET since June, has been canceled, according to TVNewser.

Do you know what else can be dangerous? Leaving the previous chyron up for an entire intro of a completely different story.

The long-awaited debut of HD takes place today on MSNBC, and also signals the launch of two new day time shows – “Morning Meeting with Dylan Ratigan” from 9-11amET and “Dr. Nancy,” hosted by Dr. Nancy Snyderman (Noon-1pmET).
