The keywords you've listed are trending due to a combination of significant anniversaries for classic horror films and the release of new content based on popular works by Stephen King.

Firstly, "The Shining" is experiencing renewed interest because it's celebrating its 45th anniversary in 2025. This milestone is being marked with special events, such as screenings at the Timberline Lodge, which served as the exterior of the iconic Overlook Hotel in the film. Additionally, a new 4K steelbook edition of the movie is being released. The film also consistently ranks among the most searched horror movies, especially around Halloween, indicating its enduring popularity. The character "Dick Hallorann" from "The Shining" is likely trending alongside the film due to this heightened attention.

Secondly, a major factor for keywords like "it movie," "it chapter two," "it chapter 2," "bill skarsgård," "pennywise," "derry show," and "it welcome to derry" is the recent premiere of "IT: Welcome to Derry." This is a new prequel series to Stephen King's "It," which began airing on October 26, 2025. Bill Skarsgård reprises his role as Pennywise the Dancing Clown in this series, generating excitement among fans of the previous "It" films and the original novel. New episodes of the show are being released weekly, with one even being released early for Halloween, keeping the franchise in the spotlight.

Lastly, "the thing" has also seen a resurgence in interest, partly due to its 40th anniversary in 2022, which led to special re-releases in theaters. The continued popularity of classic horror cinema, particularly during the Halloween season, helps maintain its presence in trending searches. The overarching reason for many of these trends is the lasting influence of author Stephen King, whose beloved stories continue to be adapted and celebrated, leading audiences to explore his wider body of work and related horror classics.
