Oh, the power of social media. Its forces seem to elude the global powerhouses that try and fail repeatedly to contain it.
Take Twitter, for instance. Companies use it to engage with customers and, in return, customers use it to complain publicly about poor products and services.
The worst of both worlds happened with US Airways' now-infamous tweet to a customer, @ElleRafter, who posted on Twitter about a flight that was delayed on the tarmac. The Twitterverse exploded with #NSFW ("not safe for work") hashtags, as US Airways investigated the source of the incident. Meanwhile, the customer with the delayed flight seemed to be able to take the shocking Twitter response in stride.
Here are 10 tweets from big brands that led to company apologies, including the most recent snafu by US Airways.
In response to the pornographic photo that showed a toy airplane and a naked body, US Airways issued a statement that read, "We apologize for the inappropriate image we recently shared in a Twitter response.
