You've got to do your research, Simon Cowell, before you stick your X Factor build-a-groups with names like One Direction or InTENsity. At the very least, you should probably run a Google and Myspace and Soundcloud or Bandcamp or whatever-they're-using-now check, just to make sure you're not naming your cute British guys after some California pop-punk band. That would be utterly dreadful, and it could get you utterly, dreadfully sued.
This has now happened. One Direction, the aforementioned California pop-punk band, has sued One Direction, the aforementioned cute British guys, as well as Cowell's Syco Entertainment and Sony Music for trademark infringement (the U.S. band applied to trademark the name in Feb. 2011). They're asking the British One Direction to stop using that name in promotional materials and are also seeking a share of the profits they've earned and more than $1 million in compensation. Neither Cowell nor Syco has commented at this time.
Before you take any stances, let's put aside for now the question of whether there's room for two Directions and do a side-by-side listen. It took a little while to find the U.S. group (award for most plausible headline I found not actually about this band: "Punk Band No One Has Heard Of Just Hit The Publicity Jackpot"), but their site's at www.onedirectionusa.com--the "USA" bit becoming increasingly meaningless as these British guys pull off their invasion--and they've got some official songs on YouTube.
And y'know? If you're listening to Hot Chelle Rae and like them, there's every reason in the world you could like these guys too. You might end up liking one of the bands under a different name, but hey.
(Surprise! That's from Up All Night. But it's not TOO different, you know?)
