Happened to see these two tvcs in the past few days and I thought they had a strong similarity. Sports was the theme and the fact that they both try and talk about the fusion of music from non-conventional instruments.
See if for yourself – Sony Ericsson W350i and Samsung F480. Let me know what do you think.

I don’t think the two are very similar though they both use sound and sport. i think the samsung ad is way better because it captures the spirit of the games better.
by the way, when i first saw the sony ad i thought it was a Dolby rip-off. you know the Dolby ad that runs at PVRs before films. it’s ditto. i mean they use the same objects to generate the noise… err music 🙂
Rip-off!
