Twitter unveils new 'business-friendly' design

San Francisco—Twitter has redesigned its Web interface and updated its mobile apps to help businesses attract more attention to their brands.

The new Twitter Web design features more customizable backgrounds and bigger profile photos appearing across devices. The new features "will give all Twitter users a richer canvas to showcase themselves and drive stronger engagement across platforms," Twitter said, on its blog.

Twitter's updated mobile apps will mimic the new Web design's photos and backgrounds, but with a prominent single brand photo. Photo streams will now display the brand images people have shared on Twitter, the company said.
