Digital Music News released a list of the most popular P2P applications in Q4 2007.
More than 100,000 PCs are polled every month and LimeWire, which uses the Gnutella network, tops the list with an installbase of 36.40%. µTorrent ranks second with 11.30%, followed by BitTorrent at 4.60%, Ares at 4.06% and Azureus at 4.30%.
In our research we found that LimeWire is far and away the single most popular P2P application. In September of 2007 LimeWire was found on 17.8% of all the PCs polled that month (also referred to as the attachment rate). With regards to market share - counting only those users with at least one P2P application on their systems - LimeWire held a 36.4% share, meaning one out of three P2P users has LimeWire on their system. These numbers are up slightly from September 2006 when LimeWire held a market share of 34.1%.
µTorrent adoption boomed during this period. In September of 2006 µTorrent was found on 1.5% of all PCs polled, good for a 3.0% market share. By September 2007, µTorrent held an attachment rate of 5.6%, which gave it an 11.3% market share. In less than a year µTorrent became the king of the BitTorrent clients, surpassing former top BitTorrent client Azureus by May of 2007.
Two new applications to look out for are FrostWire and Pando. Both have made significant gains over a nine month period and so far their growth is similar to the early rise of µTorrent. It will be interesting to see if they can sustain this growth in the coming months.
