Welcome to the Tech Mem Ride Home for Friday, July 6, 2018. I'm Brian McCullough.

Today, Sonos files for an IPO, Netflix Sunset's movie reviews, the iPhone is getting new

colors, the memes are safe for now, and the weekend long read suggestions.

Here's what you missed in this second half of the week in

tech.

Wireless speaker company Sonos has filed for an IPO to raise $100 million and begin trading on the NASDAQ under the symbol S-O-N-O.

The fun of any IPO filing is of course the S1, which gives us a look at the underlying business of a private company for the very first time.

Sonos, which has been around since 2002, reports that it has sold 19 million products to nearly 7 million households

around the world. If you do the math on that, that means that Sonos has sold an average of three speakers per customer, which is a good

indication that once people try Sonos, they tend to double down.

As far as its most recent numbers in the six months from October 2017 to the end of March of this year,

Sonos said it generated $655.7 million in revenue and reported net income of 13.1 million. But the downside, as Sonos carefully

notes in its filing is that the company does not have its own smart speaker system, instead choosing to integrate other systems,

a la Alexa.

So the problem would be if someone like Amazon decided to someday revoke access to their smart assistant software, something that definitely could happen someday.

And one other interesting detail, Sonos made note that a full-on trade war with China could be a big risk factor in the very near future,

which as Tony Tassil notes on Twitter could be the type of warning that we see from a lot more IPO candidates going forward.

Here's an odd little story.

Beginning July 30th, you will no longer be able to post reviews on Netflix and by

mid-August Netflix will remove all existing user reviews of movies and TV shows

etc. Earlier this year Netflix actually removed its long-time one to five-star rating feature

and replace that with a simple thumbs-up or thumbs-down metric.
