Example Input: In 1868, the horse-drawn tram company Compania de Tranvias al Paso del Molino y Cerro created the first lines connecting Montevideo with Union, the beach resort of Capurro and the industrialized and economically independent Villa del Cerro, at the time called Cosmopolis. In the same year, the Mercado del Puerto was inaugurated. In 1869, the first railway line of the company Ferrocarril Central del Uruguay was inaugurated connecting Bella Vista with the town of Las Piedras. During the same year and the next, the neighbourhoods Colon, Nuevo Paris and La Comercial were founded. The famous to our days Sunday market of Tristan Narvaja Street was established in Cordon in 1870. Public water supply was established in 1871. In 1878, Bulevar Circunvalacion was constructed, a boulevard starting from Punta Carretas, going up to the north end of the city and then turning west to end at the beach of Capurro. It was renamed to Artigas Boulevard (its current name) in 1885. By Decree, on 8 January 1881, the area Los Pocitos was incorporated to the Novisima Ciudad (Most New City).

Example Input: After World War II, two new competing formats came onto the market and gradually replaced the standard "78": the 33 13 rpm (often just referred to as the 33 rpm), and the 45 rpm (see above). The 33 13 rpm LP (for "long-play") format was developed by Columbia Records and marketed in June 1948. RCA Victor developed the 45 rpm format and marketed it in March 1949, each pursuing their own r&d in secret. Both types of new disc used narrower grooves, intended to be played with smaller stylustypically 0.001 inches (25 m) wide, compared to 0.003 inches (76 m) for a 78so the new records were sometimes called Microgroove. In the mid-1950s all record companies agreed to a common recording standard called RIAA equalization. Prior to the establishment of the standard each company used its own preferred standard, requiring discriminating listeners to use pre-amplifiers with multiple selectable equalization curves.
Example Output: What two formats replaced the 78?
