I don't know whether this is a trend outside Australia, but one type of ad that annoys me no end are the ads that try to make out some corporation or another is an integral part of your community or worse, your family. Car dealerships and credit unions seem to be the worst offenders, so much so that it's become something of a drinking game at my university: someone starts singing one of the ad jingles (and we know all of them) and everyone has to keep drinking until they've finished the song. Anyone who hasn't finished their drink is out, and the next round begins. The songs usually go like this:
"It's nice to know you've got a friend,
Someone you can rely on
When times are hard, we're there for you,
A caring hand to see you through;
John Davis Motors
You've got a friend for life."
There's another one from my region run by the Northern Inland Credit Union who are so desperate to be anything other than a bank that they've picked some local celebrity that no-one has ever heard of to try and perpetuate the notion that they've been a part of the community for decades and will continue to do so. The ad is literally five minutes long (the majority of ads go for thirty seconds at most), is obviously the most expensive ad the region has ever seen and is full of smarmy "warm" references that make little kids want to run. It's like that oily uncle that you only invite to your wedding because he's your uncle.
