I've had my Sky TV Box for nearly four years now (see Icons passim). It doesn't get a lot of use these days, but I have discovered that you can also get Sky Box office on it. (You need to download an app.)
I am pretty much certain you couldn't do that last time I looked, and it does mean that I can watch the Anthony Joshua - Joseph Parker fight on March 31 if I pony up £19.95 (https://www.nowtv.com/sky-sports-box-office).
I may well do that as I am rather tempted by a wager on Parker if I can get 6 to 1 odds. That's an extraordinary figure for a two horse race.
