A new campaign against child abuse built around a sign that looks different to viewers of different heights has made its way onto the Viral Video Chart, entering at No. 2 and beating clips from usual viral powers such as Samsung. The sign, from Spanish non-profit The ANAR Foundation, shows only short viewers -- children -- a hotline number to call if they need help.

Another new entry on the chart was Audi's video starring the old Spock (Leonard Nimoy) and the new Spock (Zachary Quinto), introduced as "Star Trek: Into Darkness" approached its opening this weekend -- even though the movie officially has a tie-in with Mazda. The video came in at No. 4 with more than 5 million views this week.

Heineken's new "Road to the Final" campaign about the UEFA Champions League Final at Wembley Arena and Google's "Here's to the Moms" campaign, which debuted before Mother's Day, also appear on the chart.

Samsung does hold two spots on this week's chart. The company's video for its new smartphone, the Galaxy S4, saw a jump in views from last week and held its spot at No. 3. New to the list at No. 9 is the company's video for its new NX300 camera featuring Olympian and "fastest man on earth" Usain Bolt.
