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, Liam Neeson takes on an icy persona in a spot for Conservation International; Thalía, known as the Queen of Latin Pop, promotes her collection with Macy's; and Kate Hudson showcases her clothing line for Fabletics.

While Nascar advertises the environmentally friendly efforts of its Green Initiative, its star drivers Chase Elliott and Kasey Kahne compete to win Dale Earnhardt, Jr.'s vote for the Baja Blast or Pitch Black flavor in Mountain Dew's "2016 DEWcision" campaign.
