Other firms such as Groupon, which provides online coupons to its subscribers, are likely to go public soon. The return of big internet IPOs, rarities since a bubble in telecoms and internet stocks burst in 2000, and the resurgence of large mergers and acquisitions among technology firms is dividing opinion in the industry. Some veterans see a new bubble forming in the valuations of start-ups and a handful of more mature firms such as Twitter, which is still hunting for a satisfactory business model five years after the first tweet. More sanguine voices retort that many young companies have exciting prospects and that there are plenty of corporate buyers, such as Microsoft, with the money and confidence to snap up older internet firms still in private hands.
Technology, finance and China
Yet both sides agree that the internet world is being transformed by a number of powerful forces, three of which stand out. First, technological progress has made it much simpler and cheaper to try out myriad bright ideas for online businesses. Second, a new breed of rich investors has been keen to back those ideas. And, third, this boom is much more global than the last one; Chinese internet firms are causing as much excitement as American ones.
Start with technology. Moores law, which holds that the number of transistors that can be put on a single computer chip doubles roughly every 18 months, has continued to work its magic, leading to the proliferation of ever more capable and affordable consumer devices. Some of todays tablet computers and smartphones are more powerful than personal computers were a decade ago. IDC, a research firm, estimates that around 450m smartphones will be shipped worldwide this year, up from 303m in 2010.
