EMC, America Online (AOL) and RealNetworks all beat Wall Street's predictions for their respective quarterly results issued on Tuesday.
Data storage specialist EMC said sales of its enterprise products helped the company achieve a 49 per cent increase in its fiscal first quarter revenue to $1.82bn.
Net income rose 23 per cent to $332m, or 30 cents per diluted share, surpassing the 29 cents a share prediction of analysts polled by First Call.
The figures were also boosted by EMC's Data General division, formed after the acquisition of the midrange systems developer during the fourth quarter of 1999.
EMC said sales of its enterprise storage systems and software had achieved year-on-year growth rates of 31 per cent and 74 per cent, respectively.
AOL, whose merger with Time Warner is expected to close in the autumn, reported fiscal third quarter revenue of $1.84bn, compared to $1.25bn a year ago.
A gain of $275m from sales of investments boosted its net income to $438m, or 17 cents a diluted share, compared with a profit of $411m, or 16 cents a share, last year.
Excluding the extraordinary item, net income reached $271m, or 11 cents a share, beating Wall Street's estimates of nine cents a share.
The ISP's subscription revenue jumped 33 per cent to $1.15bn while sales from advertising, commerce and other sources more than doubled to $557m.
RealNetworks also saw its revenue nearly double, but charges related to its acquisition of internet download management software company Netzip tipped net income further into the red.
Revenue for its fiscal first quarter topped $53.5m compared with $24.4m a year ago. Pro forma net income reached $8.8m, or five cents a share, against a loss of $500,000, or break even results, during the same period last year. Analysts had expected four cents a share.
However, charges related to its Netzip purchase widened its loss to $18.8m, or 12 cents a share, compared with last year's loss of $1.1m, or one cent a share, which also included extraordinary items.
The streaming media company said it downloaded more than 62 million unique software packages to consumers in the first quarter, an increase of 175 per cent from a year ago, and that international users constituted 25 per cent of its sales.
