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 here ran on TV for the first time over the weekend. 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 releases, the Portland Trail Blazers' Damian Lillard shows retired NBA star Tracy McGrady what it means to be a rookie in Foot Locker's spot to promote the Adidas Originals line, while Best Buy pushes the power of wifi during the holidays in a plug for Nikon's DSLR camera. And Apple drops a touching new commercial that is also a Creativity Pick of the Day and one of the weekend's most engaging, in which a girl turns a classic recording by her grandmother into a duet.
