Team assignment. 

Step 1. Pick a particular brand and search for 4/5 (one per team member) TV commercials for that brand from around the world. 

Step 2. Assess the ads: How do they differ? What do they have in common? Differences/overlaps could be in terms of target market, slogan, visuals, music, use of celebrities, and so forth. Speculate on the possible reasons for your findings. 

Step 3. Prepare a short PowerPoint presentation (say, 1 page per ad; including hyperlink) summarizing your key findings.
