Spidey lost his grip on the top of the national home video sales chart after just one week due to the newly released Adam Sandler comedy “Blended,” a theatrical underperformer distributed by Warner Bros.

The film, which costars Drew Barrymore, only grossed $46.3 million in theaters, but demand for the Blu-ray Disc and DVD was enough to vault it straight to No. 1 on Nielsen VideoScan’s overall disc sales chart for the week ending Aug. 31, sending Sony Pictures’ “The Amazing Spider-Man 2” to No. 2.

It was a narrow victory: Nielsen data shows “The Amazing Spider-Man 2,” in its second week of release, sold 99.7% as many copies as “Blended” its first week out.

“The Amazing Spider-Man” remained at No. 1 on Nielsen’s dedicated Blu-ray Disc sales chart, where “Blended” debuted at No. 3.

Anchor Bay’s “The Walking Dead: The Complete Fourth Season” debuted at No. 3 on Nielsen VideoScan’s First Alert sales chart, which tracks combined Blu-ray Disc and DVD sales, and No. 2 on the Blu-ray Disc-only chart.

The season-six set of another popular TV show, “Sons of Anarchy,” from 20th Century Fox, debuted at No. 4 on First Alert and No. 5 on the Blu-ray Disc chart.

Lionsgate’s “Divergent” remained in the top five on both charts its fourth week in stores, landing at No. 5 on First Alert and No. 4 on the Blu-ray Disc chart.

“Blended” generated 34% of its total first-week sales from Blu-ray Disc, which in turn accounted for 56% of second-week sales of “The Amazing Spider-Man 2.”

As for the TV shows, Blu-ray Disc accounted for 38% of total unit sales of “The Walking Dead” and just 21% of total unit sales of “Sons of Anarchy.”

On Home Media Magazine’s rental chart for the week, “The Amazing Spider-Man 2” remained at No. 1, with “The Other Woman,” from 20th Century Fox, moving up to No. 2 now that its 28-day holdback from Netflix and Redbox is over.

“Divergent” slipped a notch to No. 3, while Universal Studios’ “Sabotage” and Warner’s “Transcendence” also each moved down a spot to finish the week at No. 4 and No. 5, respectively.
