Venue: Radio City Music Hall, the annual site of NBC/NBCUniversal's Upfront (next Monday) and where MTV will return late summer for its Video Music Awards. Few venues of this grandeur (more than 5,000 seats) surpass Radio City when it comes to stagecraft and cutting-edge graphic displays. Popcorn and soda (as in whole bottles) were distributed among attendees en route to their seats and monitors were set up around the lobby for latecomers. Grade: 5 Jacks
Presentation: Previously, YouTube would operate its showcase like a variety hour -- opening performance or video, followed by remarks, then a celebrity guest spot, and so forth. In a radical departure (some might conclude gamble), the format came off like a two-act play. Act One consisted of announcements, testimonials and videos (roughly 45 minutes), with Act Two largely one big round of performances. The opening portion could have induced many on hand to groan, and didn't, thanks to the balance of YouTube executive patter and videos. Chief Executive Susan Wojcicki stressed two points in particular. First, the YouTube-watching universe of smart TV sets and TV-connected devices is now a force to be served. Second, being a content carrier open to all creators and platforms carries great responsibility. "There isn't a playbook for how open platforms operate at our scale," she acknowledged. "But the way I think about it is it's critical that we are on the right side of history." Grade: 4 Jacks
News: The unscripted original programming movement that kicked off the last Brandcast will expand over the coming months, after the first batch of originals elicited more than 700 million views. Best Shot, a high-school basketball documentary series from LeBron James, will be an early addition to the YouTube Originals lineup, along with If I Could Tell You Just One Thing (inspirational advice forum with Quantico star Priyanka Chopra) and Training Days (soccer training satire with Jack Whitehall, sponsored by Wendy's). Will Smith, currently involved with One Strange Rock on National Geographic, will celebrate his birthday September 25 with The Jump Off, a live special where he will bungee jump from a helicopter over the Grand Canyon.

Hosts: Wojcicki and Chief Business Officer Robert Kyncl handled the first-half proceedings in comfortable fashion, while YouTube celebrity Tyler Oakley (pictured above) moved the second half along. Grade: 3.5 Jacks
Star Time: A set of all-out music and dance montages, featuring a group of YouTube personalities from Postmodern Jukebox to Lia Kim, pumped the place up with substantial help from Radio City's graphics and technical crews. That gave way to super talent on the rise Camila Cabello (pictured below) singing her chart-busting hit "Havana" and a three-song closing set from superstar Ariana Grande. In between, The Daily Show host Trevor Noah thanked Kanye West for providing a new source of humor, while comedian/actress Anna Akana (star of current YouTube Red dramedy Youth & Consequences) documented how YouTube has increased the media spotlight of Asian-Americans. "I no longer had to be frustrated by the lack of diversity on the screen, because now I had the opportunity to write and produce the authentic stories I wanted to tell," she said. "There is no glass ceiling. There is no suit telling me there are no bankable Asian stars, and no bit parts." Grade: 5 Jacks
