To nitpick your nitpick, one could argue that "TCP/IP" is the name of a protocol suite, which contains more than just the two protocols that make up its name. UDP and ICMP are obviously also included. Its precise boundaries are unclear, and some may argue that other protocols such IGMP, DCCP, SCTP, DNS, DHCP, ARP, etc, form part of that suite as well.
This is nitpicky, but I think a lot of traffic considered part of 'The Internet' UDP as well these days.
