Some of Elvis Presley's early singles on Sun Records might have sold more copies on 78 than on 45. This is because the majority of those sales in 1954–55 were to the "hillbilly" market in the South and Southwestern United States, where replacing the family 78 rpm player with a new 45 rpm player was a luxury few could afford at the time. By the end of 1957, RCA Victor announced that 78s accounted for less than 10% of Presley's singles sales, essentially announcing the death throes of the 78 rpm format. The last Presley single released on 78 in the United States was RCA Victor 20-7410, I Got Stung/One Night (1958), while the last 78 in the UK was RCA 1194, A Mess Of Blues/Girl Of My Best Friend (1960).

Ah, so.. 45 rpm player was a luxury few could afford at the time

 Macao: The event was held in Macau on May 3. It was the first time that the Olympic torch had traveled to Macau. A ceremony was held at Macau Fisherman's Wharf. Afterward, the torch traveled through Macau, passing by a number of landmarks including A-Ma Temple, Macau Tower, Ponte Governador Nobre de Carvalho, Ponte de Sai Van, Macau Cultural Centre, Macau Stadium and then back to the Fisherman's Wharf for the closing ceremony. Parts of the route near Ruins of St. Paul's and Taipa was shortened due to large crowds of supporters blocking narrow streets. A total of 120 torchbearers participated in this event including casino tycoon Stanley Ho. Leong Hong Man and Leong Heng Teng were the first and last torchbearer in the relay respectively. An article published on Macao Daily News criticized that the list of the torchbearers could not fully represent the Macanese and that there were too many non-athletes among the torchbearers. (some of whom had already been torchbearers of other sporting events)
