Overall, Cadbury has produced a successful integrated communications campaign. Aside from the mild controversies, they have created a campaign which appeals to its target market and utilises a range of media from outdoor to online.

The campaign has proven to be effective with B&T reporting that the Joyville train ad alone engage with over 13 million consumers in Australia. Ben Wicks, GM Marketing for Cadbury told B&T: "We're very please and honoured by the response we've had to the Joyville campaign. The campaign has exceeded our expectations, and we couldn't be happier with the results."

This proves the success of the campaign and personally I believe it is a result of the Joyville campaign, throughout all media, making sure it developed and continually reinforced a relationship between Cadbury and it's customers.

Globally, the Joyville campaign has included outdoor advertising and art. In New Zealand, Saatchi & Saatchi Sydney teamed up with artist Iaan Buchanan to create a 3D chalk-art experience to the public. Buchanan talks about how he integrated his art into the campaign "The campaign is very visually joyful and playful in its spirit, from a marketing perspective consumers will be seeing a range of activities that will bring the Joyville story into their lives and amplify the joy that the brand brings." A cast of Joyville workers were also on site to take photos with and interact with the public, another key feature consistent throughout the campaign.

Throughout the campaign there has been some controversy surrounding both the products being promoted and the TVC's. 

Many people have voiced their opinions that the Joyville campaign and the TVC's in general are irritating and don't compare to the previous creative and quirky advertising of the past, such as the gorilla and dancing eyebrows ads. 

Another controversy surrounding the campaign came to light when a disgruntled consumer claimed that the Joyville campaign was misleading consumers. The complainted featured on the ABC's The Checkout, highlighting the fact that the Cadbury Dairy Milk blocks had been reduced from 250g to 200g, only for the Joyville campaign to increase the blocks by a 'generous 10% more joy' to 220g. Cadbury attempted to defend themsleves but the damage was already done.

Cadbury has used TVC's to reach a large audience and promote the Joyville campaign, the very first Joyville TVC was aired a year ago and was used to introduce the public to the campaign and the general concept of Joyville.

Since then, the well-integrated TVC's have been used to promote the Marvelous Creations product line, the Special Delivery sales promotion, the 10% more joy in each block and of course the continual association between Cadbury Dairy Milk and the concept of joy itself.

One of the most impressive, integrated TVC's is the Joyville train ad, it shows a giant purple Joyville steam train making its way through the Sydney suburban rail network. The TVC particularly focuses on the train's arrival into Redfern station and the excitement created when the Joyvilleworkers begin to hand out free blocks of Cadbury Dairy Milk.

There was some mild controversy surrounding the Joyville train TVC, as commuters were delayed and had to take other means of transport, some took to twitter to vent out their frustration.

The TVC's are well integrated and follow the style of the Joyville campaign 'with a focus on beautiful rich colours and polished vision, capturing interactions between the Joyville workers and members of the general public.' Turning the Special Deliveries into TVC's was also a well though out integration technique, linking the ads with other elements of the campaign.

Customer-orientated sales promotions is another tool which was used earlier this year in the Joyville marketing campaign. They ran Special Delivery competition, giving away 1,000 blocks of Cadbury Dairy Milk per day  and giving 6 Australian's the opportunity to win what brings them joy, completely made out of Cadbury Dairy Milk chocolate.

To enter, customers had to purchase a block of Cadbury Dairy Milk and the visit the website to enter. This not only encourage sales but also got the customer visiting the website discussed earlier and interacting the Joyville, and becoming increasingly apart of the campaign.

This sales promotion was very well integrated, the major prizes were not only delivered in Joyville themed cars by Joyville themed people but two of the Special Deliveries were turned into 15 second TVC's creating a buzz with the campaign.
