Save ‘Shadowhunters’ S3b countdown: Sacrifice
We’ve partnered with the amazing folks at @BoomBitchesSH to help raise awareness around the historic marketing that the Shadowfam have been doing for Shadowhunters season 3b. Today we reveal the first part of the exclusive 3b poster.
Freeform canceled Shadowhunters after season 3 on June 4, 2018, though the network ordered additional episodes to close out the story in 2019. Fans responded by launching coordinated campaigns that kept the series visible across multiple cities and platforms.
In anticipation of the Spring launch of the second half of the show’s third season, fan-led campaign group @BoomBitchesSH booked a billboard campaign in Los Angeles to advertise the show for a month (starting February 11th) as well as spread the #SaveShadowhunters message.
Campaign Timing and Premiere Context
Season 3B premiered on February 25, 2019, after an extended mid-season break that followed the cancellation announcement. The LA billboard campaign launched earlier that same month to build momentum ahead of the return. The run of episodes concluded on May 6, 2019, marking the series finale rather than a continuation into another season.
Poster Reveal and Artwork Details
The poster formed part of a coordinated fan marketing push timed to the 3B premiere window. A prominent fandom figure created the design, and the finished artwork circulated widely in the weeks leading up to the February return. Daily reveals rolled out across social channels, giving supporters incremental glimpses of the full image before the episodes aired.
Legacy of the #SaveShadowhunters Campaign
Global billboards in Times Square, Seoul, and Toronto, along with London bus banners and a plane banner over Netflix headquarters, generated widespread attention and trended on social platforms. Smaller-scale efforts kept pressure on networks through targeted advertisements and direct gifts to cast and crew. The scale of activity demonstrated how a dedicated audience could sustain visibility even after an official end date.
Fan Campaign Tactics and Logistics
Smaller campaigns focused on direct outreach to networks while also delivering cupcakes, balloons, and flowers to the cast and crew. Proposals for larger spectacles, such as a drone light show over Los Angeles, were considered but ruled out because of prohibitive costs. The group coordinated crowdfunding, vendor negotiations, and ad placements to keep every element within the budget raised by supporters worldwide.
Post-Series Fan Activity and Petitions
After the 2019 finale, new petitions targeting Netflix and Hulu appeared in 2026. Social media conversations about possible returns or reboots continue, though no official revival has been announced. The persistence of these efforts reflects the same grassroots energy that drove the original 2018-2019 campaigns.
Shadowhunter Universe Beyond the Show
Cassandra Clare has released additional Shadowhunter books and collections through 2025. Author events, including appearances at BookCon 2026, maintain an active connection between readers and the broader universe. These print projects operate separately from the television series yet keep the fandom engaged with new material.
The 2019 billboard campaign and poster reveals represented one chapter in a longer story of organized fan support. While the series itself concluded after season 3B, the coordinated efforts around #SaveShadowhunters left a visible record of how audiences can shape conversation even after a network decision.
