Problem: YouTube:

Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform. In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. According to GlobalWebIndex, YouTube was used by 35% of smartphone users between April and June 2013, making it the third most used app.

For behold, the days are coming when they will say, 'Blessed are the barren and the wombs that never bore and the breasts that never nursed!' Then they will begin to say to the mountains, 'Fall on us,' and to the hills, 'Cover us.' For if they do these things when the wood is green, what will happen when it is dry?"[Lk. 23:28-31]

Old Low Franconian or Old Dutch is regarded as the primary stage in the development of a separate Dutch language. The "Low" in Old Low Franconian refers to the Frankish spoken in the Low Countries where it was not influenced by the High German consonant shift, as opposed to Central and high Franconian in Germany. The latter would as a consequence evolve with Allemanic into Old High German. At more or less the same time the Ingvaeonic nasal spirant law led to the development of Old Saxon, Old Frisian (Anglo-Frisian) and Old English (Anglo-Saxon). Hardly influenced by either development, Old Dutch remained close to the original language of the Franks, the people that would rule Europe for centuries. The language however, did experienced developments on its own, like final-obstruent devoicing in a very early stage. In fact, by judging from the find at Bergakker, it would seem that the language already experienced this characteristic during the Old Frankish period.
What's another name for Old Frisian?
A:
Anglo-Frisian
