Reception and sales Various sources estimated the sales figure on launch day alone at approximately 50,000, exceeding analyst's expectations. BlackBerry announced in its quarterly earnings that half a million PlayBook tablets were shipped in the first quarter. However, after lukewarm market reception, there were reports that the company allegedly revised its second-quarter estimates from 2.4 million down to 800,000 – 900,000 units. Following several months of poor sales, BlackBerry started discounting the price of Playbook from its original retail price to improve the product's run rate at retail. In December 2011, BlackBerry took a $485 million write-down to account for offering price discounts. Sales improved in subsequent quarters as a result. According to Strategy Analytics figures in the 2011 second quarter, the PlayBook's market share in the middle of 2011 was 3.3%, compared to iOS (iPads) by Apple with 61.3%, Android by Google with 30.1%, and various Windows by Microsoft with 4.6%. However, the PlayBook remained relatively popular tablet in Canada during earlier years, accounting for nearly 20% of the tablet market in Research In Motion's home country in a report released in July 2012. Strong discounting of the older Wi-Fi PlayBooks resulted in strong sales in the UK during Christmas 2012.
