Every weekday, we bring you the Ad Age/iSpot Hot Spots, new and trending TV commercials tracked by iSpot.tv, a company that catalogs, tags and measures activity around TV ads in real time. The New Releases ran on TV for the first time yesterday. The Most Engaging ads are showing sustained social heat, ranked by SpotShare scores reflecting the percent of digital activity associated with each one over the past week. See the methodology here.

Among the new spots, DirecTV tries to be nonjudgmental about guys who date marionettes, Subway continues to plug its new Flatizza menu offering, Nissan sends a 2014 Nissan Rogue running with the bulls, and IBM -- which was in the news yesterday for acquiring Silverpop -- serves up new installments of its updated "Smarter Planet" campaign. Ad Age's Seth Fineberg has the story about how more than 50 individual spots will be running only once over the course of five days.
