A rulebook rewritten every season
No other show in this canon rewrites its own format this often — new voting systems, new team structures, a full rebrand, a cross-country relocation. This ranks eighteen seasons by how much each swing actually changed the show you tuned into.

The 18, in order.
- #01
The show relocates entirely and lets judges decide eliminations alone.
Production moves to Atlanta, the open-call tour gives way to video submissions, and eliminations run on judges' votes with no public ballot. The most complete rebuild the format has attempted in a single season. - #02
A full rebrand narrows the field to dancers eight to thirteen years old.
So You Think You Can Dance becomes The Next Generation for one season, with ten returning All-Stars mentoring kid finalists instead of partnering them. The format's furthest departure yet from the show it started as. - #03
The All-Stars mechanic replaces partnering with a weekly draw of returning pros.
A reduced Top 11 field draws a rotating pool of former finalists each week, one per style, instead of pairing with each other. Broadcasts go live and air in HD for the first time — the boldest swing since the debut season. - #04
Couples voting gives way to individual voting once the field hits the Top 10.
The format's biggest rule change to that point: fixed-partner voting ends midseason, and dancers get randomly re-paired every week from there. Range, not partnership, starts deciding who survives the vote. - #05
The results show disappears, and the season sets out to crown two champions.
One two-hour broadcast a week replaces the standalone results episode, judges gain a say over who dances a save solo, and the season is built from the start to name both a female and a male winner. - #06
Home viewers stop getting a vote, and only the studio audience decides.
Returning after a three-year pandemic gap, the callback week shrinks from a full Academy to a single day, and for the first time the televised vote belongs to the room, not the couch. - #07
Teams split by discipline instead of gender for the first time in a decade.
Stage and Street squads replace the usual men-versus-women format, each mentored by a different choreographer, while a mid-season special marks the show's tenth year on air. - #08
A two-judge panel goes permanent, and fixed partnerships stop mid-season.
Nigel Lythgoe and Mary Murphy settle into a permanent two-seat panel with a rotating guest completing the table, a structure the franchise keeps for years. Hat-drawn pairs from auditions dissolve at the Top 10, and dancers start drawing a new partner every week from there. - #09
Phone voting disappears, and the ballot moves entirely online.
Interactive telephone voting is dropped for good, with the show's website and a dedicated app taking over as the only way to vote. Callbacks relocate from Las Vegas to Los Angeles the same season. - #10
A custom-built studio wires 120 cameras into the audition round.
A purpose-built set nicknamed SYTYCD Hollywood debuts with a bullet-time camera rig, and televised auditions welcome a live studio audience for the first time in the show's run. - #11
A Vegas training camp becomes the callback structure every later season copies.
A new host and a six-judge rotating panel arrive alongside a 116-dancer callback week at a Las Vegas hotel — the template the franchise leans on for years after. The audition machine finds its permanent shape here. - #12
The adult competition returns, and former finalists move from partners to judges.
After a season built entirely around kid dancers, the Top 10 format comes back for adults, with ten All-Stars now judging and mentoring instead of dancing alongside the finalists. - #13
The field returns to twenty, and fans can vote online instead of just by phone.
A reduced eleven-dancer season gives way to the classic twenty again, and the All-Stars mechanic narrows to a late-round fixture. Text and online voting open for the first time alongside the phone lines. - #14
The competition runs past nine weeks for the first time in the show's history.
Eleven competitive weeks make this the longest live-show stretch the format had attempted, with the single-broadcast structure from the year before holding steady throughout. - #15
The only season the show ever airs in the fall instead of summer.
A September-to-December broadcast window replaces the usual summer run, an experiment the format reverts the very next year. World Series coverage even bumps two results episodes off the air entirely. - #16
A fourth chair joins the panel, and a mid-season cut tightens the field early.
Stephen 'tWitch' Boss expands the judging table to four alongside three returning voices, the format's first four-judge stretch in years. A trim before the live shows narrows the field further, in what the season itself frames as structural tuning rather than reinvention. - #17
The audition tour skips New York for the first time in the show's run.
Six cities replace the usual stop lineup, and a guest judge steps back from the panel over a conflict of interest with a competing dancer. A quieter season, mostly noted for what changes at the margins. - #18
The open-call format every later season measures its rewrites against.
No celebrities, no professional partners — just open auditions in three cities and a live public vote deciding who stays. Every structural swing this format has tried since starts from the rulebook this season writes.
