Worth noting that these articles are from 2019 and there hasn't been much talk of 5G TVs since. Aside from plain old 5G hype, SK Telecom wants 5G TVs as part of their envisioned ATSC/5G convergence that would bring more OTT services to broadcast TV (using their 5G network, naturally). This is mostly for the Korean market, since in North America broadcast TV is less popular and 5G networks have less capacity.
