The American brands are of course much longer established, and have more iconic logos. The ABC logo hasn't changed much since the 60s, CBS's even older, all that changes is the font of their wordmark. NBC's modern version of the peacock dates from the 80s (though it's a simplified version of an older logo) and Fox's wordmark has been in it's current form since the early 90s, though the original version from the 80s wasn't drastically different. Compare to the UK networks - the current BBC logo only dates from a couple of years ago, though it's based on a logo from 1997. The logo is an evolution of ones they've used since the 60s though. The Channel 4 logo dates from 1982 when they launched, and ITV and Channel 5's logos are 10 and 7 years old respectively. Channel 4 is the only one whose logo and ident soundtrack are comparable to the US networks, as they're actually older than the Fox Network itself and NBC's current logo.
