Long after his passing, Dr. King continues to be branded through the mediums of literature, theater, music, memorials, art and more. Musically, none of the various songs that have honored MLK have been as significant as Stevie Wonderâ€™s â€œHappy Birthday,â€ which was created to regenerate support for the campaign to make Dr. Kingâ€™s birthday a federal holiday and reached No. 2 on the UK pop charts. On Broadway, â€œThe Mountaintop,â€ in preview sales alone has grossed $1,526,258 in ticket sales with an 85% average attendance rate. The Rev. Martin Luther King, Jr. National Memorial cost approximately $120 million. Also, many visual artists have works set to debut in homage of Dr. King, including creative artist, Beau McCallâ€™s ambitious 6-series button crown project. â€œHis legacy has infinite possibilities to be retread and reinvigorated through new media and pop culture,â€ states Peterson.
