Years ago CBS did a New Years across America broadcast that carried parts of several parades including the Tournament of Roses, Philadelphia's Mummers parade and some others. That got dropped years ago.
NBC has been the heritage broadcaster for a very long time (including the game). When the Rose Bowl moved to ESPN/ABC broadcasts, ABC began broadcasting the parade too. Recently, NBC coverage was a half hour less, due to a dog competition. They no longer have that and went a full 2 hours.
WPIX/NY used to simulcast KTLA''s broadcast. I can remember Bob Eubanks doing the hosting (The Newlywed Show host). Since Tribune's sale, that hasn't happened. I guess WPIX's owners (Mission, oops, Nextstar) has decided against airing simulcasts anymore.
