This might be the nicest thing I’ve ever said about Comcast but I think their slow roll-out approach was better (from a PR perspective) than what facebook is doing. There was no big bandaid pull where Comcast was suddenly Xfinity it just sort of... happened?
Did it really happen though? I still see stuff with Comcast on it. Like technician trucks, random web pages, postal mailings, etc. It seems to me that they just came up with the term Xfinity and then slowly associated it back with the Comcast name, so now both Comcast and Xfinity can be thought of as terrible companies.
