The basis for the entire growth of the dial-up Internet:

   V.32 / 33 / 34  9600bps / 14.4 kbps / 33.6 kbps analogue dial up modems
   V.42/43/44 compression and error correction protocols for modems
   V.90   56kbps analogue dial-up modems

The basis for the explosive growth of residential broadband Internet around the world:

   G.992.1  ADSL v1
   G.992.3  ADSLv2
   G.992.5  ADSL2+
   G.993.2  VDSL2

The basis for FTTP deployments, including the NBN fibre
   G.984   G-PON
   G.987   10G-PON


The basis of the global mesh of terrestrial and submarine optical fibre cable
backbones carrying the Internet between cities, countries and continents:

    G.652 / 653 / 654 / 655  Characteristics of various types of single-mode optical fibre
    G.657 bending-loss insensitive single-mode optical fibre - the basis for most
recent FTTP connections within the premises
    G.694.1  DWDM spectral frequency grid
    G.707   SDH interfaces (and related family specs)
    G.709  &  G.959.1 OTN systems and physical interface rates, wavelengths up to 100 Gbps
         

Plus a few minor protocols like:

   G.711 - fundamental coding of digital telephony, providing crystal clear global
speech for 25 years or so
   G.729    8kbps compressed voice, the main CODEC for most VoIP services - yes, even
SIP-based services as well as H.323 and H.248
   H.323 - Voice and video conferencing system, brought to the masses in the original
Microsoft Netmeeting software many years before SIP became popular


The vast majority of Internet bits travelling more than a few hundred metres is
carried over ITU-specified protocols and media.
ITU protocols and standards have been pretty successful in layers 0 - 2, not so much
layer 3 and higher, with the exception of things like G.729.

The IETF doesn't really touch layer 2 or lower ("IP over everything"), so that 'simple
5 layer model' you talk about is ITU-T (or IEEE Ethernet)  for layers 0, 1 and 2, and
IETF for 3 and 4 only.



(Which isn't to say that I think the ITU taking over the administration of the
Internet is a good thing - I don't - but administration is a very different beast from
defining technical standards)
