Here in Brazil, TV Globo has been using "The Fuzz", in many variations, as the theme for its main evening newscast, Jornal Nacional (the first nationally-broadcast television newscast in the country, and still the most-watched) since it first aired, in 1969:

The previous version of the theme has been in regular use for 28 years, between 1989 and 2017 (being the longest-running version of it):

And the current version, despite being used on a regular basis since 2017, was first used in 2002 or so, for major news events, such as the US-led attacks on Afghanistan, presidential inaugurations (such as when Luiz Inácio Lula da Silva was first sworn in as president, in 2003):

...and announcements of the new Pope (like this 2013 video from when Francis was announced as the Pope):

Over at Band, the theme for its main evening news, Jornal da Band, has been in use since 2005:

It was first refreshed in 2007, when the broadcast switched to HD (being, with RedeTV! News, one of the first national newscasts in Brazil to be broadcast in high definition):
