Several billion years ago, give or take a few billion, a few neutrons decided to get together with a few protons and form what has been called the Big Bang, which pretty much started the universe as we know it. As things cooled down stars, galaxies, and planets were born. On the planet we know as Earth some primordial ooze became cozyu with their amino acid friends, creating the baseline needed for life. At about that same time this season of America's Got Talent premiered aired on NBC.

Okay, I may be exaggerating a bit here, and my science may be slightly off, but it does seem to me that AGT has been on the schedule a bit too long. Premiering on June 17th, most of the shows that aired before the Olympic break have been just the tryouts. Only the very end of July and first few weeks in August dealt with the callbacks and elimination of those initially chosen by Piers, Sharon and the Hoff. Finally, we are now into the live competitions and eliminations, which means two nights of AGT a week for the next several weeks. According to the schedule posted at NBC's media site, that puts the finale of the show around October 1st! Nah, that can't be right.

On a regular basis, we get press releases sent to us here in the palatial penthouse suites of TV Squad. Most of them are your standard write-ups about a upcoming series or television event that can't be missed. Others, while they seem to print all of the necessary information, actually have an underlying subtext to them, arousing curiosity about what the networks and/or studios are not revealing.

Take the recent press release from BBC America that mentioned the beginning of filming on the newest series of Torchwood. The press release mentioned the subtitle of the series, Torchwood: Children of Earth, and that this newest series (actually, mini-series ... only five episodes) will focus on one single adventure that has the team battling for the future of the human race. The release also mentioned the return of John Barrowman as Captain Jack Harkness, Eve Myles as Gwen Cooper and Gareth David-Lloyd as Ianto Jones.

Look, I'm just going to go ahead and take credit for this one. Obviously Britney listened to me when I praised her for her awkwardly funny VMA promos with this year's host, Russell Brand, and agreed that that was enough for this year. Her manager, Larry Rudolph, has confirmed that despite reports, Brit will not be picking up the sparkly underwear from the cleaners in order to perform at this year's VMAs.

Fans of unruly extensions and gum-smacking need not fear, however: there is still a good chance that Ms. Spears will make an appearance at the fête. Britney is nominated for Video of the Year for her single, "Piece of Me." Even though Britney Spears has been nearly synonymous with MTV and the VMAs for most of her career, she's never actually won one of the coveted moon men, so I'm not sure how good her chances are of actually making an acceptance speech. Regardless, I wouldn't be surprised if producers still find something for her to do during the show; if there's one thing for which Britney can always be relied on, it's creating buzz. Well, that and single-handedly keeping Cheetos in business.

The MTV Video Music Awards air on September 7.

In a media crossover, People magazine is coming to TV screens. ABC has scheduled an hour-long special called Half Their Size: The People Magazine Weight Loss Challenge for Sept. 30 at 10 p.m.

The franchise began in People in 2002, and focuses on folks who need to shed more than a few pounds -- preferably, half their size. Obviously, the magazine stories have been a big hit, since anything about losing weight is always a big hit.

The show will focus on eight residents of Mississippi -- the nation's "heaviest" state -- for a nine-month period to see how their lives change through diet and exercise.

Robert Llewelyn, best known to Red Dwarf fans as the android Kryten, has confessed on KTSC-TV in Seattle that the BBC has commissioned a one-hour special of Red Dwarf to film in October. For those keeping track, Red Dwarf hasn't been on television since 1999.

This may be a mistake. On one hand, eight seasons of the show was beating a dead horse. It stopped being good after season three. On the other hand, nine years is certainly enough time for creators Rob Grant and Doug Naylor (or whomever they designate) to write an hour's worth of new quality material.

It's also possible that enough of a nostalgia vibe would exist to make the one-hour special successful. I call it the Star Wars effect. It is where bad entertainment is accepted as good and sells like mad because a certain name is attached to it (see Star Wars Episode IV: The Phantom Menace for a good example. Or better yet, don't).

I have a tween-aged girl in the household, so we watch a fair amount of Disney Channel. I'll come clean and even announce that Miley Cyrus, The Cheetah Girls, and Demi Lovato share iPod space with AC/DC, Jeff Beck, and Aerosmith. Hey, those Disney Channel tunes are catchy, and they're easy to dance, I mean, walk to. I draw the line at the Jonas Brothers, though.

But about 10 minutes into the new Cheetah Girls: One World movie the other night, my daughter looked at me and said, "I was really hoping these Cheetah Girls movies would get better." Yeah, me, too.

I actually liked the first two movies, in 2003 and 2006, respectively. The second, directed by High School Musical alum Kenny Ortega, was a downright cute tale about the Girls' escapades in Spain.

If you've been watching NBC's Olympic coverage, you must have seen all of the promotion they have been doing for their fall season. New shows My Own Worst Enemy, Crusoe, Knight Rider, Kath & Kim, and America's Toughest Jobs have all had plenty of play. As have the returning Chuck and Life. Given that the latest Olympiad is closing in on becoming the most watched television event of all time, you might think those promo spots were pretty valuable.

Apparently, not so much. The Hollywood Reporter runs down the record for the network promoting new shows during past games. In 2004, the Athens games led to one show, Joey, making it beyond its first season. Likewise for the Sydney games in 2000, which brought us Ed, and nothing else. Things were a little better in 1996 from Atlanta. Profiler, The Pretender, and Suddenly Susan all lasted another four years. Not a stellar track record and it leaves you thinking that those precious spots might have served the network better pitching more beer. It has the makings of a good poll though. After the jump, place your vote for the one new show that will make it out of season one.

Dancing With the Stars is a show that makes no sense to me. I understand the appeal of it; I'm usually very interested in any program that involves celebrities doing ridiculous things on national television and I know that people love bright shiny costumes, but it still somehow manages to hold no interest for me whatsoever.

With that said, I know that the announcement of each season's DWTS cast is heavily anticipated and rumored for months before the actual announcement. We heard that Dan Marino may be a contestant; a claim that was soon denied. 82-year-old Cloris Leachman was another name floated, as was Magnum, P.I. himself, Tom Selleck. Kim Kardashian and Kathy Griffin were also said to have been approached.

As with most rumors, some of these turned out to be false, but others had some truth to them. Follow me after the jump for the official (and completely insane) cast of Dancing With the Stars' seventh season, along with some twists the producers have cooked up for this go-around.
