As I write this from TCA, let me tell you about about the TCAs: The former is the TV Critics Association summer press tour; the latter is the Teen Choice Awards (Fox, 8 p.m.), which brings confusion every year (at least in my circles).

For the most part, kids know that it’s the second TCAs they’re most interested in. John Cena and Victoria Justice host the event tonight which will feature performances from Charlie Puth, Flo Rida and Seraph from “Empire.” They’re giving Justin Timberlake a decade award.
