WEEI again lost the Celtics broadcast rights in 2001, this time to WWZN. Entercom reacquired the rights to the broadcasts in 2005; initially heard on WRKO, Celtics games moved back to WEEI in 2007 (though Celtics coaches and players appeared on WEEI regularly during WRKO's time as flagship). In April 2005, WEEI began streaming its broadcasts live online by way of a free membership at its official website; a previous stream was offered from 1997 until 2002. The exception is for Red Sox and Celtics games, as these are streamed only through the team and league websites as part of subscription packages. Around the same time, the station again lost ESPN Radio programming when the affiliation was acquired by WAMG and WLLH; the station then expanded an affiliation with Fox Sports Radio that began in 2002.
