Background: 8090 is a seven member Chinese (mainland) boy band formed in 2010 By EEMedia, the same company affiliated with Top Combine, Wei Chen, I Me and tons of other popular artists. They haven't officially debuted yet, but they've been performing since they were formed and have a few songs of their own, as well as a gorgeous photobook which I wish I had the technology to scan and upload. A few of the boys have also taken part in an upcoming drama, Runaway Sweetheart, which is scheduled to start airing (finally) this week! They also starred in the short spin-off drama Hello Summer, which aired this past summer. Their fanclub's name is Feng Che (Windmill). They want to help carry the boys’ dreams to the entire world.
"Like their seniors Top Combine, 8090 is also a boyband formed from Superboys contestants. Unlike Top Combine, 8090 was formed under the scrutiny of the public eye during the course of the Superboys 2010 competition. Originally having a whopping 36 members, 7 final members remain after months of intense training and selections." (Direct quote taken from the 8090 thread on Cfensi, linked below.)

The OP of Runaway Sweetheart by 8090. Zhang He is the only 8090 member to make an appearance (he's the boy floating in the air and attacking the girl, lol), but the two main actors are Chen Xiang (boy at computer) and Chai Ge (boy in bed) are both singers/actors affiliated with EEMedia, and Jiang Chao is supposed a main character as well though he doesn't show up here.
I would include more videos but between being at work and it being really difficult to sort through videos and find ones of just the final members, it isn't happening right now.
However, I'd recommend checking out the following Viki channels! The first is for Hello Summer, the short spin-off drama from last summer. It's eight episodes at ~15 minutes each and is completely subtitled. The second is for Runaway Sweetheart, which doesn't have much yet but should become much more active soon!
