<span class="s1">Bauuer’s <em>Harlem Shake</em> – a repetitive piece of dance music sent stratospheric by a goofy 30-second viral video – just spent its fourth consecutive week at No 1 on the Billboard Hot 100 and its reign has marked a new era in pop music.</span> Billboard changed its rules the week of <em>Harlem Shake</em>'s release, so that "user-generated clips that utilise authorised audio" count towards a song's rankings, sending Bauuer's track instantly to the top spot. Although Billboard's editorial director Bill Werde announced recently that the formula is, "generally speaking", fairly evenly split between sales, airplay and streaming, commenters have pointed out that adding crowdsourced virals skews the chart in a way that privileges certain types of music – novelty pop, notably – over others. <span class="s1">If 2012 was the year the video-driven pop hit broke, with Psy and Carly Rae Jepson coming from nowhere to become global stars, 2013 will doubtless be the year it goes mainstream, with music-industry marketeers scheming a way to create gimmicky videos for established acts so irresistibly dorky that the rest of us can’t help but watch a dozen times, and then get together with friends to tape our own version. </span> Only time will tell whether the advent of the ultra-corporate viral video will spell the death of these clips as a fun, whimsical democratic format. <span class="s3"><strong>Autumn 1996 – </strong></span><span class="s4"><strong>Dancing Baby is the internet's first viral video meme</strong></span> <span class="s5">A 3-D animation of a dancing baby goes viral via email and winds up a few years later on <em>Ally McBeal</em> and <em>The Simpsons</em>. A dance group called Trubble make the Top 40 in the UK with <em>Dancing Baby (Ooga-Chaka)</em>.</span> <span class="s3"><strong>November 2005 – </strong></span><span class="s4"><strong>YouTube makes video sharing mainstream</strong></span> Three PayPal employees set up the company, start beta-testing in May and launch that winter. A year later, it is bought by Google for US$1.65bn (Dh6bn) in shares. <span class="s3"><strong>January 2007</strong></span><span class="s4"><strong> – Justin Bieber is YouTube's first star</strong></span> A 12-year-old Bieber sings a Ne-Yo jam at a talent show; his mother records it and uploads the video to YouTube. On the strength of this and other clips, Usher signs the singer to his label. By 2010, Bieber's <em>Baby</em> is the most-watched video on YouTube. <span class="s3"><strong>June 2009</strong></span><span class="s4"><strong> – Video phones popularise user-generated clips</strong></span> <span class="s5">Apple releases the iPhone 3GS, its first phone capable of capturing video as standard. User-generated videos spike; six months later, YouTube reaches a billion page<br/> views per day.</span> <span class="s3"><strong>March 2011</strong></span><span class="s4"><strong> – Rebecca Black parodies colonise the web</strong></span> <span class="s5">Black’s vanity music video, <em>Friday</em>, goes viral after being called “the worst video ever made”. What was originally called “cyber-bullying” works out in Black’s favour: she was covered by Katy Perry, Justin Bieber and the cast of <em>Glee</em> and is reported to be working on a debut album.</span> <span class="s3"><strong>September 2011</strong></span><span class="s4"><strong> – Bieber clip makes Carly Rae Jepson a star</strong></span> <span class="s1">The <em>Canadian Idol </em>runner-up first releases <em>Call Me Maybe</em> back in 2011, but it’s not until February 2012, when Justin Bieber makes a fun, low-spec YouTube video of himself singing along to the song with a group of friends, that the song takes off. It becomes 2012’s best-selling single worldwide.</span> <span class="s3"><strong>July 2012</strong></span><span class="s4"><strong> – Gangnam Style smashes records</strong></span> <span class="s5">Psy’s satirical pop hit overtakes Bieber’s <em>Baby</em> as the most-watched YouTube video ever and has a billion views by the end of the year. Notable spoofs include <em>Eton Style</em>, by boarding-school students, and <em>Johnson Style</em>, by Nasa astronauts.</span> <span class="s3"><strong>February 2013</strong></span><span class="s4"><strong> – Five Aussie teens reshape the pop industry</strong></span> <span class="s1">An obscure dance song called <em>Harlem Shake </em>is used as the backing for a short, silly video by a group of Queensland teenagers. It becomes the first truly grassroots viral hit and the song goes to No 1 in the US after Billboard changes its rules. Versions are uploaded to YouTube by everyone from the daytime TV show <em>Today</em> to Pepsi.</span> <span class="s3"><strong>March 2013</strong></span><span class="s4"><strong> – Corporations take the reigns</strong></span> <span class="s5">The ad agency behind “Just Do It” makes its own quirky video of a moonwalking pony to promote a European mobile-phone network. It racks up 5 million hits and the song that accompanies it, Fleetwood Mac’s <em>Everywhere</em>, returns to the UK singles chart for the first time in 26 years. Expect this pattern – big corporations making weird, homemade-looking videos, both for pop acts and other clients – to run and run.</span> <span class="s2"><strong><a href="mailto:artslife@thenational.ae">artslife@thenational.ae</a></strong></span> Follow us on <a href="https://www.facebook.com/thenationalArtsandLife">Facebook</a> for discussions, entertainment, reviews, wellness and news.
