Wikipedia says TCP is from 1974 (https://en.wikipedia.org/wiki/Transmission_Control_Protocol https://en.wikipedia.org/wiki/Transmission_Control_Protocol). That would mean it turns 50 next year.
There likely are way older protocols in telephone networks.

That would mean it turns 50 next year. Yes, but 1974 TCP is completely incompatible with the current TCP. In the original 1974 version of TCP – https://datatracker.ietf.org/doc/html/rfc675 https://datatracker.ietf.org/doc/html/rfc675 – they hadn't yet split TCP and IP out into the separate protocols. I'm not sure what is the earliest version which is interoperable with contemporary TCP/IPv4 – probably either the 1981 version – https://datatracker.ietf.org/doc/html/rfc793 https://datatracker.ietf.org/doc/html/rfc793 – or the 1980 version – https://datatracker.ietf.org/doc/html/rfc761 https://datatracker.ietf.org/doc/html/rfc761 TCP/IP first entered into widespread production use on 1 January 1983, when ARPANET switched over to it from the earlier (incompatible) NCP protocol. The version of it adopted at the start of 1983 had been finalised in 1981/1982. Prior to that, it was only used on a research/experimental basis, which meant that incompatible changes were frequent.
