This was the first Academy Award ceremony intended to be broadcast via satellite worldwide , but according to Klaus Lehmann , a foreign sales executive of the ABC television network , in addition to Canada and Mexico ( broadcasting the event since 1953 , but only live since 1964 ) , only two South American countries , Chile and Brazil , roughly in the Oscars ' time zone , were interested in the live coverage . The Chilean television rights to the Oscars were sold by ABC International to Televisión Nacional de Chile while the Brazilian rights were sold to TV Tupi . The latter country 's rights to the TV broadcast of the Oscars were moved to a joint venture of TV Bandeirantes and TV Record . Starting in 1974 , the Brazilian TV rights to the Oscars were sold by NBC ( which had acquired the TV rights to the Awards from ABC to be broadcast for a five-year period until 1975 , when they returned to ABC for the next year 's Awards ) to Rede Globo . An early attempt to change the Academy Awards presentation 's start time to 1 p.m. to fit European television audiences was rejected by AMPAS executives . Since at the time television standards conversion was difficult , about 50 other countries did not broadcast the event live . In Europe , most TV broadcasters signed off at midnight , thus the Oscars were not broadcast live and were recorded on film and then shipped to broadcasters with a minimum 4-day delay from the awards ' broadcast date
