If you use Twitter, you may have noticed their new logo.
They have changed the shape of the familiar bird as a part of their logo & identity update and, with the new logo, comes a new set of rules.
This will most likely be disregarded by many people but, for website and social media users and designers who want to play by the copyright rules, they are important to know.
Most simply, Twitter wants their brand to be represented by the new logo, and the new logo only. They do not authorize any modifications of the size or color, or any animations or additions to the logo.
They also ask that people not use any of the older logos, or any other visual marks, to link to their brand, or to individual Twitter accounts. This includes the "chiclet" style, shown to the left, the "Twitter" logo-text with the bubble letters, and earlier customized versions of the Twitter bird and/or logo.
The Twitter Trademark & Content Display Policy on their website gives full details.
Twitter will probably not be making a big deal out of this for small individual sites, but they have gone after some larger companies for mis-use of their branding in the past and, if nothing else, updating now will keep your website and social meida pages looking freash and up-to-date as people transition over to the new logo.
Now, if you'll excuse me, I have several pages to update.
