Sony Ericsson intends to drop the Walkman and Cyber-shot brands on its mobile phones in the UK and other developed markets, according to a report on Brand Republic. It says the company’s new ‘Entertainment Unlimited’ proposition – which was introduced earlier this year - will take the place of the separate music and photo brands. However, the forthcoming launches of the Sony Ericsson W205 Walkman and the W995 Walkman phones won’t be affected.
