2003 LEGO Sets
2003 brought challenges but also key innovations that shaped LEGO’s revival. Realistic skin tones were introduced for licensed themes, while yellow remained standard for original ones. Clikits, Designer, and expanded Sports lines reflected diversification efforts, and 4 Juniors replaced Jack Stone for younger builders. World City modernized the classic Town setting. Though financially turbulent, LEGO’s design experimentation and new audience focus paved the way for its recovery.
