The clever engineering behind the virtual yellow first-down line you seen on TV for NFL games.

Since the late 1990s, the virtual yellow line has been quietly enhancing football broadcasts by giving viewers a live, intuitive guide to the state of play. The graphic is engineered to appear painted on the field, rather than simply plopped on top of the players, so it doesn't distract from the game at all.

The line debuted during a September 27, 1998, game between the Baltimore Ravens and the Cincinnati Bengals. It was developed by a company called Sportvision Inc. and operated by six people in a 48-foot semi-truck parked outside the stadium.

ESPN was the only network that immediately agreed to pay the steep price of $25,000 per game. Before long, other companies began offering the yellow line to the other networks, and now you won't see a football game without it.

My uncle works for Sportvision and he gets to travel to all the games to setup the lines and other animations. I, also, was able to do a job shadowing with him and the technology that goes into this is insane.

They don't use it for ads because there is a four hour long ad called the superbowl

Broadcasting live sports is about so much more than getting the right camera angle. Season 3 of Observatory goes behind-the-scenes with the audio engineers who mix some of the biggest sports games: https://ufl.ae/videow/TbeBeVt3Glm

I remember when it first came out and it would paint the line over the players when they passed it, now you can’t rven tell it looks like it belongs there

So they did that to the puck before 2000, and they never moved to puck line technology in hockey? With that put aside entirely my balance and wight problem of the puck may have.

Wish it was there in real life,

Weird, I remember that in some NFL games in the early 2000's there were ads that would flash on the field for like, 3 seconds (in the same way as the yellow line) advertising AOL

Hidden parking rules hurt our cities. Will Chilton and Paul Mackie of Mobility Lab explain.

The cities we live in are shaped by the way we get around them. Over the past 60 years, with more and more people opting to drive cars, the need for parking spaces has increased with the boom in driving.
To accommodate that demand early on, cities and towns started requiring developers to include parking with their new buildings after World War II. These policies, known as mandatory parking minimums, set precise standards for parking spaces for each building. And these parking spaces don't come cheap.
