AJ MICHALKA, TRACEY GOLD, DAVE COULIER, BRONSON PINCHOT, DEMARCUS WARE, TOM ARNOLDHoward Cosell is no longer around to announce the current version of “The Battle of the Network Stars” (ABC, 9 p.m.) but there are a few vintage names — Tom Arnold, Bronson Pinchot, Dave Coulier and Tracey Golden, Joey Lawrence, among others, in the competition that first aired in 1978.

In the new version, competitors tend to be from a single network — ABC and its sister stations Disney Channel and Freeform. And yet another sister network, ESPN, supplies the hosts, Mike Greenberg and Joe Tessitore.

The third season of the scripted summer sci-fi series “Zoo” (CBS, 10 p.m.) picks up 10 years after the animals were cured, but at the cot of sterilizing the human race. And now there’s a new threat in some lab-made creatures.

The first Head of Household is named on the season’s second episode of “Big Brother” (CBS, 9 p.m.), which has already taken some weird turns and kicked out its nerdy fanboy player. Not sure this group is interesting enough to watch two hours of the live unedited “Big Brother Live” (Pop, 1 a.m.) which starts tonight.

I loved the first episode of “The Gong Show” (ABC, 10 p.m.) because it knew just how stupid it was. And the host approaches performance art.

But there’s a lot of reality shows and game shows among the new stuff on network TV tonight, from “Beat Shazam” (Fox, 8 p.m.) and “Boy Band” (ABC, 8 p.m.) to “Hollywood Game Night” (NBC, 8 p.m.), “Love Connection” (Fox, 9 p.m.) and “The Wall” (NBC, 9 p.m.).

Sonny implicates his daughter as a subject on “The Tunnel: Sabotage” (PBS, 9 p.m., check local listings).

As summer gets hotter here, it gets more freezing on “Yukon Men: Roughing It” (Animal Planet, 9 p.m.) and “Mountain Men” (History, 9 p.m.).

“Cyrus vs. Cyrus” (Bravo, 10 p.m.) finally involves Miley, just in time for the first season finale.

Friends plot to teach a disrespectful friend a lesson on “Murder Among Friends” (Investigation Discovery, 9 p.m.).

On “Million Dollar Listing New York” (Bravo, 9 p.m.), Ryan gets an expensive listing in Tribeca.

Scarlett’s pregnancy garners her some unexpected attention on “Nashville” (CMT, 9 p.m.).

A chunk of the Titanic’s hull is examined on “Mysteries at the Museum” (Travel, 9 p.m.). “Mysteries of the Outdoors” (Travel, 10 and 10:30 p.m.) opens up a whole new realm of possibilities.

An injured participant on “Alone” (History, 10 p.m.) wonders if seeking medical help will mean his shot at winning.

Reginae’s birthday spirals out of control on “Growing Up Hip Hop Atlanta” (WeTV, 9 p.m.).

Two strippers fight over a client on “Sin City Justice” (Investigation Discovery, 10 p.m.).

“Impossible Engineering” (Science, 10 p.m.) looks at some projects in Japan.

There’s an amusement park disaster on “The Night Shift” (NBC, 10 p.m.).

“Vintage Flip” (HGTV, 11 p.m.) is not a compilation of Flip Wilson clips. Instead, it’s about renovating mid-century homes to sell.

This year’s BET Awards (BET, 8 p.m.) gets a replay.

The month-long Thursday night salute to gay Hollywood on Turner Classic Movies closes with “Who’s Afraid of Virginia Woolf” (8 p.m.), “The Loved One” (10:30 p.m.), “The Year of Living Dangerously” (1 a.m.), “Torch Song Trilogy” (3:15 a.m.) and “Valentino” (5:15 a.m.).

Baseball includes Oakland at Houston (MLB, 2 p.m.), St. Louis at Arizona (MLB, 5 p.m.), Minnesota at Boston (ESPN, 7 p.m.) and Dodgers at Angels (MLB, 10 p.m.).

In golf, first round play comes in the U.S. Senior Open (Fox Sports 1, 2 p.m.).

The WNBA has Seattle at Connecticut (ESPN2, 8 p.m.).

And in a FIFA Confederation Cup semifinal, it’s Germany vs. Mexico (Fox Sports 1, 2 p.m.).
