The document discusses 4 marketing ideas from SxSWi 2012:
1) New applications of social media like ambient social and social TV.
2) The power of "transmedia" storytelling across multiple platforms.
3) Crowdsourced messaging that incentivizes external networks to create content.
4) Creating products instead of just ads to positively impact consumer lives.
The key takeaways are to adapt to changing social media uses, leverage multi-screen strategies, involve customers in campaigns, and build products people want over clever ads. An open mindset is needed given shifting consumer and technology trends.
