American Broadcasting Company [SEP] International development
The first attempts to internationalize the ABC television network dates to the 1950s, when Goldenson tried to use the same strategies he had in expanding UPT's theater operation to the international market. Goldenson said that ABC's first international activity was broadcasting the coronation of Queen Elizabeth II in June 1953; CBS and NBC were delayed in covering the coronation due to flight delays. Goldenson tried international investing, having ABC invest in stations in the Latin American market, acquiring a 51% interest in a network covering Central America and in 1959 established program distributor Worldvision Enterprises. Goldenson also cited interest in Japan in the early 1950s, acquiring a 5% stake in two new domestic networks, the Mainichi Broadcasting System in 1951 and Nihon Educational Television in 1957.
