Thanks to Marvin Plevinski for providing this information to the table tennis fans.
“As you may know, NBC is covering the Olympics. However, besides the main network, there are several other NBC family networks covering the games. They include NBCSN, USA and CNBC. I did not see any matches on the main NBC channel. Some of the matches start today but they are on the NBC APP over the internet. The following link is for the daily match schedules and some of the blocks will indicate the network where it will be televised. Here is the site link:
