Let me stop from writing about the TCAs for a moment to talk about the TCAs.

It’s been a bit of a mixup this weekend that the reporters tweeting about the TV Critics Association summer press tour have been using the same hashtag as the kids anticipating the Teen Choice Awards, which occur tonight.

Those feeding their Bieber Fever have instead been getting messages about upcoming PBS programs on the Civil War.

For a time TV writers were sure that their coverage of the press tour was the top trending topic on Twitter. We’ll find out for sure after the broadcast tonight of the Teen Choice Awards 2012 (Fox, 8 p.m.).

Demi Lovato and Kevin McHale co-host the event in which surfboards replace trophies for winners. Both are affiliated with Fox shows: she, as a new judge on “X Factor”; he as wheelchair kid on “Glee.”

They’ll award winners in categories from choice movie stealer to choice web star.

The band No Doubt will perform for the first time in a while and other performances are scheduled from Carly Ray Jepsen, Flo Rida and yes, Jason Bieber.

It’s the attention on the young cast members that diminishes Matt Le Blanc’s role in “Pucks” on a new episode of “Episodes” (Showtime, 10:30 p.m.).

Emily Maynard makes her choice on the finale of “The Bachelorette” (ABC, 8 p.m.), moved to Sunday as part of ABC’s maneuvering to thwart a competing dating show on CBS this week.

It will be a long for her, and for us. After choosing between the two men she is left with, with platitudes and buzzwords (“this journey”) that are endlessly repeated, she may realize she’s eliminated the crowd into two men she doesn’t want to spend her life with after all. And then there’s a live “After the Final Rose” (ABC, 10 p.m.) in which she can talk about it.

With less fanfare and considerably less airtime, “Food Network Star” (Food, 9 p.m.) has its own finale, choosing among four finalists Justin Warner of Brooklyn and Martie Duncan of Birmingham, Ala., both on Alton Brown’s team; Michele Ragussis of Brooklyn, who was Bobby Flay’s candidate, and Yvan Lemoine of Maspeth, N.Y., the only remaining member of Giada  De Laurentiis‘s team.

Chris Meloni’s life as a vampire leader was a short one, and now vampire king Russell Edington may be going after the guys who were aiding him on a new “True Blood” (HBO, 9 p.m.).

Having seemingly demolished the Mexican cartel that was controlling him, Walter White now has to deal with the Germans who backed him on an episode of “Breaking Bad” (AMC, 10 p.m.) promised to be as striking as last week’s season return.

A new episode of “The Newsroom” (HBO, 10 p.m.) takes on a story of international tension. And the competing “Political Animals” (USA, 10 p.m.) negotiates for hostages.

There’s an awful lot on for a Summer in late July, including a third new Inspector Lewis caper on “Masterpiece Mystery!” (PBS, 9 p.m., check local listings).

Funny to hear from Mary-Louise Parker on how strict she is with her own children (no Skittles for them) considering her role on “Weeds” (Showtime, 10 p.m.).

Last week, he was up on the block; tonight Frank is head of household and gets to make his own nominations for eviction. In the meantime, there’s word that Willie has been taken out of the house for good because of his actions.

The charm of a local place is dismantled in the season two premiere of “Bar Rescue” (Spike TV, 9 p.m.) invades Silver Spring, Md., where a team led by nightlife consultant Jon Taffer turns the Piratz Tavern into a spot with a far less fun name, Corporate Bar and Grill.

Ten Olympic stars of the past are interviewed on “Oprah’s Next Chapter” (OWN, 8 p.m.).

There’s a seven-hour marathon of “NCIS” (USA, 3 p.m.).

Roxy goes into labor on a new “Army Wives” (Lifetime, 10 p.m.).

Here’s a battle you don’t want to be promoting: the time slot choices of “Mob Wives” (VH1, 8 p.m.) vs. “Jerseylicious” (Style, 8 p.m.).
