Watch Steve Jobs Present the First-Ever 'Stevenote' in 1984

The Apple Macintosh was introduced to the public at the Boston Computer Society on January 30, 1984, but the film was nearly lost to history. No digitized versions of the film existed until January 2014, and much of the footage existed only on U-matic cassettes. Thanks to the hard work and investment of BCS co-founder Jonathan Rotenberg, videographer Glenn Koenig, Software Arts co-founder Dan Bricklin and the Computer History Museum, a vintage recording was recovered and made available to the public on the event's 30-year anniversary.

This BCS presentation was a precursor to the huge media events we're accustomed to now and, being in 1984, preceded by more than a decade the 1998 iMac introduction event commonly cited as "the first Stevenote." For the first time, the entire Apple Computer crew demonstrated easy-to-use home computing programs such as MacWrite; discussed innovative developments such as dot matrix printing(!), which allowed users to print images at home for the first time; and extolled the virtues of point and click, copy and paste, and easy image manipulation. One notable selling point early in the video touts the portability of the 3.5-inch floppy, which could fit 400k of storage "right into your shirt pocket." There are also great moments in Apple advertising history here, as many of the early-'80s commercials are included in the presentation.

The version of the film below is edited to remove dead space (and to include clearer images of slides and projected video), but is still fairly lengthy at an hour and a half. If you're interested in tech history at all, it's well worth the watch. And if you're interested in the preservation project itself, there are details on Bricklin's website, in Rotenberg's announcement at the Computer History Museum, and in Harry McCracken's post at TIME.

How Google Chrome’s New Built-In Ad Blocker Will Change Your Browsing Experience

If you can’t stand web ads that auto-play sound and pop up in front of what you’re trying to read, you have two options: Install an ad blocker on your browser or avoid the internet all together. Starting Thursday, February 15, Google Chrome is offering another tool to help you avoid the most annoying ads on the web, Tech Crunch reports. Here’s what Google Chrome users should expect from the new feature.

Chrome’s ad filtering has been in development for about a year, but the details of how it will work were only recently made public. “While most advertising on the web is respectful of user experience, over the years we've increasingly heard from our users that some advertising can be particularly intrusive,” Google wrote in a blog post. “As we announced last June, Chrome will tackle this issue by removing ads from sites that do not follow the Better Ads Standards.

That means the new feature won’t block all ads from publishers or even block most of them. Instead, it will specifically target ads that violate the Better Ad Standards that the Coalition for Better Ads recommends based on consumer data. On desktop, this includes auto-play videos with sound, sticky banners that follow you as you scroll, pop-ups, and prestitial ads that make you wait for a countdown to access the site. Mobile Chrome users will be spared these same types of ads as well as flashing animations, ads that take up more than 30 percent of the screen, and ads the fill the whole screen as you scroll past them.

These criteria still leave room for plenty of ads to show up online—the total amount of media blocked by the feature won’t even amount to 1 percent of all ads. So if web browsers are looking for an even more ad-free experience, they should use Chrome’s ad filter as a supplement to one of the many third-party ad blockers out there.

And if accessing content without navigating a digital obstacle course first doesn’t sound appealing to you, don’t worry: On sites where ads are blocked, Google Chrome will show a notification that lets you disable the feature.

Why Subliminal Messaging Doesn't Work (Unless You Want It To)

Subliminal messages—hidden phrases in TV programs, movies, and ads—probably won't make you run out and join the Navy, appreciate a band's music, or start smoking. That's because these sneaky suggestions don't really change consumer behavior, even though many people believe otherwise, according to Sci Show Psych.

We say "don't really" because subliminal messages can sway the already motivated, research shows. For example, a 2002 study of 81 college students found that parched subjects drank more water after being subliminally primed with words like "dry" and "thirsty." (Participants who weren't already thirsty drank less.) A follow-up experiment involving 35 undergrads yielded similar results, with dehydrated students selecting sports drinks described as "thirst-quenching" over "electrolyte-restoring" after being primed for thirst. Experiments like these won't work on, say, chocolate-loving movie audiences who are subliminally instructed by advertisers to purchase popcorn instead.

Learn more about how subliminal messaging affects (or doesn't affect) our decision-making, and why you likely won't encounter ads with under-the-radar suggestions on the regular.
