T-Online, Germany's biggest internet service provider, is back in profit, helped by an increase in the number of broadband customers.
The company's earnings before tax, investment and one-off costs amounted to 76m euros ($87.4m; £54.4m) in the first three months of 2003, up from a 14.5m euro loss in the same period of last year.
Pre-tax profits at the firm, majority-owned by Deutsche Telecom, edged into the black too with a 2m euro profit after a 92m euro loss in 2002 on sales up 22% to 445m euros.
The company said the growing popularity of broadband connections and economies of scale were improving its profitability, and losses at operations outside Germany were falling.
T-Online has come a long way from the dot.com bust.
Together with its French rival Wanadoo - a unit of France Telecom - it has managed a consistently above par performance in recent months.
Shares in the two companies have risen by more than a quarter since the start of 2003.
In both cases, the performance of the subsidiary has eclipsed that of the parent.
