Korean-based celebrity news and media website, Allkpop has gained an online following on Twitter during the last few hours thanks to a viral marketing campaign that encourages people to use the microblogging site to post about the entertainment news site. Allkpop is running a competition where people who include the term #allkpop in their 140 characters could win music CD and DVD giveaways.
The topic #allkpop appears to have since been removed from Twitter's list of trending topics.
The low-budget horror film Paranormal Activity is proving to be a crowd-pleaser in both the cinemas and with people on Twitter. The movie has been consistently in Twitter's list of most talked about topics since before it's limited release in art-house cinemas in the US at the end of last month.
Since then, viral marketing has driven the film into the mainstream market. An online campaign saw over one million people vote for Paranormal Activity to have a US-wide release.
"Paranormal Activity cost only $11,000 to create, and it made over $7 Million first weekend in Theatres!!! That's a come-up!!! $$$$" wrote one Twitter user.
