Many celebrities are interested in cars, often collecting and even racing classic vehicles. "Joyride" features four such celebrities -- rapper T-Pain, NASCAR driver Brian Vickers, actress Mischa Barton and actor Oliver Trevena -- who go on a quest to find the best cars in a variety of categories. Each episode focuses on a particular group of vehicles, such as best British car and best 1960s muscle car. The celebrities combine their automobile knowledge with their driving skills as they test cars to see which ones they think qualify as the best-of-class.

As chairman and CEO of hospitality company Landry's, Inc., Tilman Fertitta is in charge of a number of nationally known dining and entertainment brands, including Morton's The Steakhouse and Golden Nugget Hotels & Casinos. With these and other businesses under his purview, he has tremendous buying power with an annual budget of $2 billion, and he's looking to use it to help American small businesses highlighted in this series. In each episode, he spends time with two small businesses, sampling their products and getting to know their owners. After sharing his expertise and pushing for improvements to the firms' products, Fertitta decides whether to place a significant purchase order with one of the companies, both or neither. When Fertitta chooses a company with which to place an order, it can transform not only the business but also its owners' lives. Failure to secure an order from Fertitta, on the other hand, could be the end of the road.

Wayne Carini chases cars for a living. Not literally, but if a vehicle were an iconic Mercedes Gullwing or a luxurious Maserati Ghibli, for instance, and Carini saw it in motion, it's a sure bet he would get himself in gear and run after it. That's how much this man loves classic cars, a passion that Velocity has captured for this series since 2008. Known as a "collector car archaeologist," Carini leads viewers into the business of locating high-end automobiles stashed in homes, garages and barns in the U.S. and abroad. When he finds a gem, Carini negotiates to buy it, then resells at auction or privately. Along the way he talks shop with respected collectors, restorers and artisans.

Being the chairman and CEO of multibillion-dollar corporation Camping World takes up a lot of Marcus Lemonis' time. But when he's not running the company, he's searching for struggling businesses in need of cash. Lemonis tries to help turn each company around by offering cash for a piece of the business and a percentage of the profits. Now he's bringing that process to TV with this series, in which he puts millions of dollars of his own money on the line. Once he's working with the company, he does whatever is necessary to save the business and make a profit for himself -- even if it means firing the president. Although some of his changes could be considered radical, the companies should be willing to go along with them because in the last 10 years, Lemonis has successfully turned around more than 100 companies. To quote the not-so-humble Lemonis, "When I have skin in the game, my way is the only way your business will survive."

Torres falls back on all of his experience to get the properties, which range from single-family homes to multiunit developments, back on track.

In this series, some of those unsuccessful products are given a second chance to gain popularity. Engineers scour the country in search of items they think can make it big. They then locate the inventors, giving them resources and advice that can help take the products to the next level. After building, testing and perfecting the products, the inventors are given the opportunity to pitch their improved products with the ultimate goal of getting them on the market -- giving the inventors a second chance at making millions from their ideas.

"Adventure Capitalists" can succinctly be described as "Shark Tank" for outdoor enthusiasts. In each hourlong episode, hopeful entrepreneurs pitch the investors -- the titular "adventure capitalists" -- their ideas for new outdoor products. The investors then head out into the world, going on expeditions through a variety of challenging terrains, to experience the products firsthand to see if they live up to the entrepreneurs' claims. If the tests are successful, the potential backers can choose to make a large investment in each product. The investors who have the option to change the entrepreneurs' lives include former NFL player and TV host Dhani Jones, former Olympic skier Jeremy Bloom and American gymnast and Olympic gold medalist Shawn Johnson East.
