Which came first, Pakistan or Samsung?

Samsung came first, by 9 years. Lee Byung-chul opened a trading company in Daegu, Korea.

Side by side

Pakistan

Pakistan and India were created by the same act of parliament, but Mountbatten had to attend both ceremonies, so he took the Pakistani one in Karachi on 14 August and the Indian one in Delhi on the 15th. Pakistan is therefore one day older than India in the sense the question means. Independence in both cases took effect at the same instant: midnight between the two dates.

Samsung

Samsung began in 1938 as a grocery trading company dealing in dried fish, vegetables and noodles, which it exported to Manchuria. It moved into textiles, insurance and retail before making its first electronic product — a black-and-white television — in 1970. The name means "three stars".
