A marketing consulting firm is advising that Apple could effectively expand into the mobile phone, car stereo and television markets.
The recommendation is based on consumer perceptions of what categories well-known brands could move into.
Vivaldi Partners CEO Erich Joachimsthaler told Forbes: "These are the world's leading growth brands. But the question of how much further they can grow resides in the minds of consumers."
Other brands investigated included eBay, which has expansion opportunities in dating, loans, and skills swapping, according to the researchers. Samsung was considered to have opportunities in electric cars, alarm systems, gaming consoles, and mobile phone services.
