Article: On March 30, 2015, it was announced that West is a co-owner, with various other music artists, in the music streaming service Tidal. The service specialises in lossless audio and high definition music videos. Jay Z acquired the parent company of Tidal, Aspiro, in the first quarter of 2015. Including Beyonce and Jay-Z, sixteen artist stakeholders (such as Rihanna, Beyonce, Madonna, Chris Martin, Nicki Minaj and more) co-own Tidal, with the majority owning a 3% equity stake. The idea of having an all artist owned streaming service was created by those involved to adapt to the increased demand for streaming within the current music industry, and to rival other streaming services such as Spotify, which have been criticised for their low payout of royalties. "The challenge is to get everyone to respect music again, to recognize its value", stated Jay-Z on the release of Tidal.

Question: What music streaming service is Kanye West a co-owner of?
Ans: Tidal

Article: The alkali metal ions are small and mobile; their presence in glass allows a degree of electrical conductivity, especially in molten state or at high temperature. Their mobility decreases the chemical resistance of the glass, allowing leaching by water and facilitating corrosion. Alkaline earth ions, with their two positive charges and requirement for two non-bridging oxygen ions to compensate for their charge, are much less mobile themselves and also hinder diffusion of other ions, especially the alkalis. The most common commercial glasses contain both alkali and alkaline earth ions (usually sodium and calcium), for easier processing and satisfying corrosion resistance. Corrosion resistance of glass can be achieved by dealkalization, removal of the alkali ions from the glass surface by reaction with e.g. sulfur or fluorine compounds. Presence of alkaline metal ions has also detrimental effect to the loss tangent of the glass, and to its electrical resistance; glasses for electronics (sealing, vacuum tubes, lamps...) have to take this in account.

Question: What component gives glass the ability to conduct electricity?
Ans: alkali metal ions

Article: The show pushed Fox to become the number one U.S. TV network amongst adults 1849, the key demographic coveted by advertisers, for an unprecedented eight consecutive years by 2012. Its success also helped lift the ratings of other shows that were scheduled around it such as House and Bones, and Idol, for years, had become Fox's strongest platform primetime television program for promoting eventual hit shows of the 2010s (of the same network) such as Glee and New Girl. The show, its creator Simon Fuller claimed, "saved Fox".
