When I visited the USA I was surprised to see comparative advertising on TV. That was something I haven't seen here (Australia).
An example would be fast food ad's - they would show their burger side by side with a competitors comparing the size and cost etc. Nothing like that in Australia.
Update: Wikipedia says "In Australia, no specific law governs comparative advertising"
I am Australian. Remember those Energizer bunny commercials showing the other bunny running out of battery halfway through the race? And a quick google shows that Duracell ran a direct campaign against Eveready which was ruled ok by the courts, as well as a recent court decision in favour of Optus doing direct comparisons with Telstra for mobile phone plans.
To be clear, I do not believe the parent post who said 'this is not allowed in most countries'. I would be less surprised by a claim that this kind of advertising is uncommon in most countries.
Even in india, I hadn't seen the kind of comparative advertising which is commonplace on American TV. Very rarely, some products would compare themselves against "the leading detergent" or somesuch.
