A winner: Amazon. Amazon, Amazon, Amazon, blah blah blah. Anyways, the Seattle retailer has figured out how to get off the merry-go-round of high-price customer acquisition. Amazon Prime boasts eighty million subscribers, or 63% of US households. To put that in perspective, 44% of US households own a gun, 49% have a landline phone and 51% attend church. I think those are the same people. Amazon Prime customers spend $193 per month and are younger and more affluent than the average consumer. According to L2 research, the largest Prime category is household items including tissues and laundry detergent, followed by personal care products and baby supplies. A winner: Quora, the crowd-sourced question-and-answer site now valued at $1.8 billion. Quora has 190 million monthly users, double last year’s count. Most questions posted to Quora ask for career advice but most answers are given in the life advice category. Quora’s success demonstrates that even the most successful search algorithms can’t answer questions as well as another person. If you type “smartphone with the best camera” into Quora, you get relevant results. Type the same into Amazon and it doesn’t realize you are looking for a phone. My favorite question: how can Santa lose weight when nobody around him is supportive? Winner or loser? PetSmart for buying pet food e-tailer Chewy in what is the biggest e-commerce acquisition ever – a reported $3.35 billion dollars, $50 million more than the $3.3 billion Walmart paid for Jet.com. Chewy was the top online pet retailer last year. Chewy has double Jet’s revenue and is the market leader in online pet supplies. Chewy dominates Amazon in paid search, appearing in more Google AdWord results for pet care terms than anybody else. Compared to Jet, this looks like actually a pretty good deal. Pet care is a $63 billion market in the US. With all the controversy over Trump’s border wall, it’s worth remembering that walls never work. The Sumerians were one of the first societies to build a border wall in the 21st century BC in an attempt to keep out nomadic tribesmen. But the wall didn’t work well, as invaders figured out they could just walk around it. Constantinople also built a wall that stood for hundreds of years until the Ottomans invented the cannon. And the Great Wall of China, while you can see it from space, word is it hasn’t kept many Mexicans out. I had more jokes about walls but was worried you couldn’t get over it. Get it? Over it? Oh well, that’s the best we could do this week. We’ll see you next week.
