You may have recently received the newest Twitter layout, which I wrote about last month. If you haven't noticed a change yet, be patient. About two-thirds of the accounts I manage have it, and the others don't yet. Unlike the last update, there doesn't seem to be a way to manually upgrade to the new look.
Well if you have that new layout, you'll find that some of your favorite brands may have an expanded version of that look.
Above is an example of how the expanded page for Staples looks. Of course they've customized their background - anyone can do that - even without an easy button. They now have a banner add that runs horizontally across the top of the page, and there is expanded space for a description. There is also a space for a featured tweet, which can be a video, photo, or advertisement of some sort.
Through this, has Twitter actually found a way to finance its operations without venture capital - premium layout pages? I hope so. For more information about brand pages, and to see if this may eventually be a good option for your business, see the Twitter Advertising Blog.
