It's no surprise that Coca-Cola, as a long-time sponsor of the Olympics, created a massive PR, advertising, and marketing campaign when the Games made a much-watched journey to China this summer.

However, Petro Kacur, senior manager of marketing communications for Coke, noted that this is the first year the soft drink company sent a group of employees there to blog. Speaking to PRWeek, Kacur said 30 Coke employees, nominated by their peers, were sent to Beijing to enjoy the Games, and to relate their experiences back to co-workers via an internal blog.

"They're blogging about their experiences internally to share with other employees," Kacur said.
