While recent chart-toppers like Adele, Jay-Z and Kanye West and Beyonce didn’t much need the help, last Sunday’s MTV Video Music Awards sparked some sizable jumps in digital sales for winners and performers.

Last week’s telecast, the highest-rated in the network’s history with 12.4 million viewers, was likely instrumental in young band Young the Giant’s sudden burst onto the upper reaches of the iTunes charts. (Overall SoundScan numbers won’t reflect bumps from the kudocast until next week.) Young the Giant was the only rock band to perform on the show, and its “My Body” climbed 220% on the iTunes singles chart to reach No. 24, while their debut album climbed 220%.

Songs performed or featured on the show by Chris Brown, Adele, Beyonce and the Foo Fighters also experienced triple-digit percentage jumps on the iTunes singles chart (Brown’s “Beautiful People” climbed 904%).

Jessie J, a Brit popster who has been dutifully fighting for a space in the American pop firmament after her album “Who You Are” entered and then dropped off the charts in February, saw a 200% boost in album sales following her appearance as the kudocast’s “house artist.”

Yet numbers for the biggest potential beneficiary are still to come. Lil Wayne, who not only closed the awards but also plotted an unusual release strategy in which his “Tha Carter IV” was available for purchase immediately after the show’s end, is on track for a No. 1 bow on next week’s SoundScan album chart.
