That's why I would differentiate Pepsi's (Apple, Google, Shell, Twitter) logo update from a re-brand. Twitter is a perfect example: In 2012 they did a logo update, then in 2014 they did a re-brand -- two separate things. If you read the Uber Brand Experience page, it says it started off as a black car service. Many people today still think that Uber is competing with Taxi's but it's a "transportation network" of which the taxi aspect is a small piece. The whole goal of the re-brand is to literally lose the old brand (and nearly everything about it) and re-brand to better represent what we were going to become (as the site says).
