Question: In 2004, what are the names of the platforms where Codemasters publish its games?
SQL: SELECT T4.platform_name FROM publisher AS T1 INNER JOIN game_publisher AS T2 ON T1.id = T2.publisher_id INNER JOIN game_platform AS T3 ON T2.id = T3.game_publisher_id INNER JOIN platform AS T4 ON T3.platform_id = T4.id WHERE T3.release_year = 2004 AND T1.publisher_name = 'Codemasters'
