Plans for a massive marketing campaign by Sony, focusing on its Handycam, Cybershot and Alpha brands, have been uncovered by marketing magazine, BrandRepublic.

The campaign, which is due to break later this year, is said to be being designed around a concept currently being dubbed 'Foam City'.

The ads are currently being shot in Miami and are expected to contain images of children of adults playing in foam bubbles, located around the famous city.

According to BrandRepublic's Ed Kemp, the campaign is expected to break in June.
