The long-awaited return of “Twin Peaks” may not have been a ratings breakout during its Sunday premiere, but the show will most likely see the lion’s share of its viewership in delayed viewing.

According to Nielsen data, the two-hour premiere averaged 506,000 viewers in its initial airing and a 0.2 rating in adults 18-49 in live-plus-same day viewing. That is of course a fraction of the 34 million viewers the initial series debut pulled in back in 1990, but that was also before the rise of cable, let alone streaming.

Showtime won’t be sweating those numbers, however. The premium cabler announced that Sunday was the single biggest sign up day for their Showtime streaming service ever. The show also generated 4.7 million total impressions on Twitter, trending both in the United States and worldwide and ranking number one in prime time among all series. In addition, the show has already averaged 1.1 million viewers, when counting repeat airings, streaming, and on-demand viewing.

Immediately following the premiere, Showtime offered subscribers access to the third and fourth parts across the streaming service and on-demand. Those two hours will then air back-to-back on May 28, followed by single parts in subsequent weeks.

The revival hails from original creators David Lynch and Mark Frost with Lynch directing all 18 hours. The limited event series picks up 25 years after the people of Twin Peaks were stunned when their homecoming queen Laura Palmer was shockingly murdered.

Along with the familiar faces, the new “Twin Peaks” will feature a lengthy list of new cast members. Last year, Showtime revealed the whopping 217 actors who would appear in the series, including Naomi Watts, Amanda Seyfried, Laura Dern, Monica Bellucci, Jim Belushi, Ashley Judd, and more.
