Amazon Prime Video subscribers sit through up to 6 minutes of ads per hour

AdWeek report claims gradual uptick in ad load, which ad buyers confirm is growing.

Amazon forced all Prime Video subscribers onto a new ad-based subscription tier in January 2024 unless users paid more for their subscription type. Now, the tech giant is reportedly showing twice as many ads to subscribers as it did when it started selling ad-based streaming subscriptions.

Currently, anyone who signs up for Amazon Prime (which is $15 per month or $139 per year) gets Prime Video with ads. If they don’t want to see commercials, they have to pay an extra $3 per month. One can also subscribe to Prime Video alone for $9 per month with ads or $12 per month without ads.

When Amazon originally announced the ad tier, it said it would deliver “meaningfully fewer ads than linear TV and other streaming TV providers." Based on “six ad buyers and documents” ad trade publication AdWeek reported viewing, Amazon has determined the average is four to six minutes of advertisements per hour.

Experimental retina implants give mice infrared vision

A light-sensitive wire mesh implanted in the retina helps restore nerve impulses.

Human vision relies on photoreceptor cells in the retina that react to visible light and trigger neurons in the optic nerve to send signals to the brain. Degradation of these photoreceptors is the leading cause of vision impairments, including blindness.

However, a team of scientists at China’s Fudan University has recently built prototype retinal implants that can replace the failing photoreceptors and potentially provide infrared vision as a bonus. Sadly, they’ve only been tested in animals, so we’re still rather far away from making them work like Cyberpunk 2077-style eye augments.

Vision on chip

Earlier work on retinal implants that restored at least some degree of vision to the blind involved using electrode arrays that electrically stimulated neurons in the back of the retina, taking the place of the damaged photoreceptor cells. A patient had to wear a camera mounted on a pair of glasses that sent signals to the implant to activate this signaling. These implants required a power source to work, were unreliable, difficult to use, and had limited resolution, and the surgical procedure necessary to put them in the eye was extremely complicated.
