The fear with the first ad in this series - Vodafone delights - was that it may not have been extendible. But with the second ad in the series - Vodafone Happy Hours - they prove us wrong. I loved for 3 reasons - one, its a fresh way of communicating something new; two - it lives up to the Vodafone history of creating simple, adorable characters; and three - I like what Vodafone is trying to sell! Simple fluff heard clearly above the usual hard sell.
The radio ads - different from the TV series - also use the audio media well. Nice extension of the idea vs just repeating the audio from the TVC on radio.
The previous 'teletubbies' series was a disappointment. I think Vodafone recovered well with this campaign!
