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 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 releases, Google explains why you want its Chromecast device (it allows "For Bigger Hangtime"), while Anytime Fitness shows us a guy who decided to start going to the gym to "get to a healthier place" because "I woke up one day and I was frickin' 60." And Comcast Business introduces us to a businessman who truly loves conference calls in a wry spot promoting its VoiceEdge app.
