Samsung has been in touch about the sheep video that's taking the internet by storm.
The 2 minute 45 second spot, set near a 13th century Welsh castle called Caregg Cennen, has now had nearly 4 million hits.
According to the creators, it works online because it is "completely original and unvarnished".
The internet rewards newness - anything that pushes things to the limits," says Daniel Evans, a creative director from Viral Factory, the company that made it.
"It's respected because we were able to create it with just time and energy. It's not some glossy, unattainable advert."
It features shepherds and their highly trained dogs herding sheep (wearing jackets with LED lights on) through intricately coordinated stunts.
A total of 400 sheep were used in the unscripted video, 200 black and 200 white, and 43,000 lights.
The vid was released to help market Samsung Electronics' 2009 LED TVs - it works, they say, by linking smart dogs, smart shepherds, and the company's smart LED technology.


Ah-ha - you did do some more research! 4 million wow. Not too sure I am in total agreement with the explanation – viral advertising is mighty strong stuff.
Very posh new-look blog!
