song was a position on the "Honor Roll of Hits", introduced in March 24, 1945, initially as a 10-song list, later expanded to 30 songs, which ranked the most popular songs by combining record and sheet sales, disk jockey, and jukebox performances as determined by Billboard's weekly nationwide survey. This chart amalgamated different records of the same song by different performers as one, and topping the first chart was "Ac-Cent-Tchu-Ate the Positive". In 1955, a composite standing chart that combined retail sales, jukebox and disk jockeys play charts but counted individual record separately was created as "The Top 100" chart, with "Love Is a Many-Splendored Thing" by The Four Aces its first No. 1. This chart is the direct predecessor to the current Hot 100 chart. The jukebox chart ceased publication after the June 17, 1957, issue, the disk jockey chart after July 28, 1958, the best-seller chart after October 13, 1958, and the Honor Roll of Hits after November 16, 1963. After July 28, 1958, the composite chart the "Top 100" chart was also discontinued; and the "Hot 100" began the following week on August 4, 1958, listing "Poor Little Fool" by Ricky Nelson as its first No. 1. The Hot 100 currently combines singles sales, radio airplay, digital downloads, and streaming activity (including data from YouTube and other video sites). Many Billboard charts use this basic formula apart from charts dedicated to the three data sources: sales (both physical and digital), airplay and streaming. Billboard also publishes various music genre charts. "Harlem Hit Parade" was created in 1943 which became "Best-Selling Race Records" in 1948 and "Best-selling Rhythm & Blues Records" in 1949, and then "Soul Singles" in 1969 (currently Hot R&B/Hip-Hop Songs). "Best-selling Folk Records" was published in 1948, and this morphed into "Best-Selling Country & Western Records" in 1949, "Best-Selling C&W Records" in 1956 and "Hot Country Singles" in 1963 (now Hot Country Songs). MOR charts has been published since 1961, variously called "Easy Listening", "Middle-Road Singles" and "Pop-Standard Singles" and now Adult Contemporary. Billboard charts now cover these music genres: rock, pop, country, dance, bluegrass, jazz, classical, R&B, rap, electronic, Latin, Christian, world and holiday music, and even ringtones for mobile (cell) phones. An album chart, the "Best Selling Popular Record Albums", was first published on March 24, 1945, with The King Cole Trio its first No. 1. The first chart had 10 albums, before
