As the World Cup starts up, Twitter is looking to cash in on the several different advertising campaigns that are being promoted across its social network. To do this, Twitter has partnered with Visa and Adidas to experiment with video hashtaging. The user simply writes in a hashtag, say #allin for Adidas, and a video is automatically embedded into the tweet. It gives Twitter another monetization stream, and allows advertisers to continue to think outside of the box for social media campaigns.
