Everything Google announced at Google I/O 2015 in one handy list
That's a wrap on all things Google. In case you missed the keynote, here's a recap of all the highlights you may have missed. — Android M — Kicking off the keynote, Google Senior Vice President Sundar Pichai announced …
Context & Ripple Effects
This recap closes the loop on a well-teased event: Google had already published the I/O 2015 schedule flagging Android M, voice access, ATAP wearables, and multi-screen Chromecast games, and Ars Technica's pre-show rundown guessed at Chromecast 2 and a standalone photos product. The keynote, opened by Sundar Pichai with the Android M announcement, turned most of that speculation into an official agenda.
Why it matters beyond the checklist: this is the baseline year for everything the later coverage tracks — the assistant-and-home push that made 2016's I/O a catch-up exercise, and the 2017 edition that showcased research without much shipping product.
First-order effects
- Android M moves from scheduled session topic to announced developer preview, giving the Android ecosystem its next platform target directly from Pichai's keynote.
- The items the schedule teased — voice access, ATAP wearables, multi-screen Chromecast gaming — shift from rumor-stage coverage to confirmed Google roadmaps.
Second-order effects
- By seeding assistant, home, and VR ambitions at this I/O, Google set up the dynamic BuzzFeed later described: a 2016 follow-up where it played catch-up establishing Home, Assistant, Allo, and Daydream against entrenched competitors (playing catch-up at I/O 2016).
Third-order effects
- The pattern holds across the corpus: I/O functions as Google's annual direction-setting stage, but as Wired's 2017 verdict showed (impressive research, little practical application), announcements consistently outrun shipped product — making each year's list a leading indicator rather than a delivery report.
The trend: Google I/O has settled into an annual rhythm where keynote announcements define platform ambitions a year or more before they become products, with each edition measured against what the last one promised.
