In a series about the modern computer revolution, data and numbers crunching is everything. Unfortunately, the August 2 numbers don’t look good for Halt And Catch Fire, even with strong but diminished results from lead-in HumansThe Season 2 finale of the struggling AMC series pulled in just 485,000 on Sunday night.

While not an all-time low for the show – that was the 451,000 of June 21 – the August 2 viewership is down 16% from the 574,000 that watched the Season 1 ender on August 3 last year. Sunday’s overall viewership stumbled 17% from its July 26 and also dropped a 26% from the 659,000 that tuned in for the revamped H&CF’s Season 2 debut on May 31. All of which is a way of saying that while it was a surprise when AMC brought H&CF back for a second run last August 20, no one would be that shocked if they hit the escape button on a third season now.

Of course, AMC only like to talk about Live + 3 results – except when it comes to the blockbuster ratings of The Walking Dead – so perhaps those DVR numbers will spark some renewed interest. Last year’s Season 1 finale jumped  71% from its Live +Same Day numbers to 981,000 viewers in Live + 3. But in a second season that has seem new lows and a rough ride overall, it will be a steep climb – in more ways than one. Among adults 18-49, the August 2 H&CF pulled in 158,000 – again down from the end of Season 1. In fact the key demo attraction was down 30% from the freshman season ender and down 40% from the 18-49 draw of the Season 2 opener.

The numbers for the AMC show that looks at our digital beginnings were a big drop from the AMC series that looks at our potential digital tomorrows. Lead-in Humans, which is coming back for the second series, averaged 1 million viewers on Sunday. While more than double Halt And Catch Fire’s results, that’s down 17% overall. The Channel 4 co-pro was also down 13% among adults 18-49 to 429,000.
