Early iAd advertisers pleased with results

The first two advertisers on Apple's iAd network have said they are pleased with the results from their campaigns.

Nissan tells the Los Angeles Times that people spent an average of 90 seconds using its iAd - ten times longer than comparable online ads. Meanwhile, click-through rates were five times higher.

Meanwhile, Unilever's iAd for its Dove brand saw a "double-digit" percentage of users seeking further information about the product advertised, while 20% of viewers watched the ad more than once.

The caveat here is that these were the first two iAds, and iOS users were excited enough about them to want to watch and interact with them. They had novelty value.

The real proof of iAd's effectiveness will come a few months down the line - but this is certainly a good start.
