Which program is broadcast most frequently? Give me the program name.
SELECT t1.name FROM program AS t1 JOIN broadcast AS t2 ON t1.program_id = t2.program_id GROUP BY t2.program_id ORDER BY COUNT(*) DESC LIMIT 1
SELECT "t1"."name" FROM "program" "t1" JOIN "broadcast" "t2" ON "t1"."program_id" = "t2"."program_id" GROUP BY "t2"."program_id" ORDER BY COUNT(*) DESC FETCH FIRST 1 ROWS ONLY
