Here are some very famous brands that may not have been so successful given their intended original name. We've all heard of Jig to Cif and Ulay to Olay, but these name changes are far more radical.
Amazon, the largest Internet-based retailer in the United States, was incorporated as Cadabra in 1994 by founder Jeff Bezos. He then changed the name to Amazon in 1995 because he thought it sounded too much like cadaver - another name for a dead body!
Soft drink Pepsi was originally called Brad's drink. Created in the 1890s, it was named after Caleb Bradham, a North Carolina pharmacist who helped develop the drink. It was renamed as Pepsi-Cola in 1898.
Google, the ubiquitous search engine, began life in 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University. They named it 'BackRub', because the system checked backlinks to estimate the importance of a site.
Eventually, they changed the name to Google, which originated from a misspelling of the word 'googol', which is the number one followed by one hundred zeros.
Snapchat, the video messaging application, was first launched in 2011 under the name Picaboo in founder Evan Spiegel's father's living room. Sounds a little creepy.
A brand which needs no introduction, Playboy, was was founded in Chicago in 1953 by Hugh Hefner. He originally intended to call the magazine Stag Party, but after the unrelated men's magazine Stag sent Hefner a letter saying they would sue for infringement, he was forced to rethink.
He is said to have considered Top Hat, Gentleman, Sir and Bachelor, before his friend Eldon Sellers suggested Playboy.
Finally, Evan Williams, who co-founded social networking giant Twitter in 2006, once joked about calling it FriendStalker. Thankfully, that was thrown out.
