2012–present
Having purchased a 51% stake in NBCUniversal in 2011 and looking to revitalize their crippled brand, Comcast decided to shed the red cresent motif and adopted the 1986 NBC peacock logo on December 10, 2012. In February 2013, just two months after the rebrand, Comcast announced that they would buy the remaining 49% of NBCUniversal from General Electric, and thus take full ownership of the company.
