Ted Robinson could be with the 49ers for a long time.

Remember all the way back (a whole week ago) when the Golden State Warriors announced an extension with KNBR through the 2015/16 season? This morning, the San Francisco 49ers took dwarfed that extension announcement with an announcement of their own: their games will carried on Cumulus radio stations through 2023.

Today marks kind of a marketing bonanza (to use Joe Starkey’s favorite word, even though Ted Robinson took over as the 49ers’ play-by-play announcer and could very well stick around for the length of this extension) for the Niners, as the team is also holding a “Red and Gold Rally” at Justin Herman Plaza at noon to celebrate the opening of a new “Shop 49ers” retail store which will be open on weekdays during the NFL season. So while The City should start turning orange and black as the leaves turn in other areas of the country, the 49ers hope to also capitalize on the retail explosion that should follow, now that their 13-3 record in 2011 looks like it wasn’t a fluke.

Speaking of the San Francisco Giants, Cumulus has clearly made an aggressive move to remain atop the sports radio standings in the Bay Area. Locking down the 49ers and Warriors, added with a partnership with the Giants that shows no signs of abating anytime soon, gives KNBR’s parent company a strong foundation throughout the next decade.

Here is the 49ers’ press release on the extension:

(Santa Clara, CALIF) — The San Francisco 49ers and Cumulus San Francisco have signed a 12-year contract extension that will keep the team’s games on three of the Cumulus stations – KNBR 680, 107.7 The Bone and KGO 810 – through 2023.  The announcement was made this morning by 49ers CEO Jed York and Cumulus President and CEO Lew Dickey on KNBR 680’s Murph & Mac Show.

49ers football first aired on the Cumulus SF stations in the 2005 season, and this new agreement will carry the partnership into the team’s new Santa Clara stadium in 2014 and beyond.

“We are very excited to announce our partnership with Cumulus has been extended well into the future,” said York. “They have been an exceptional partner to date, having provided us a tremendous avenue to reach our fans through their various radio stations and first-rate programming. As we move closer and closer to the opening of the new Santa Clara stadium, the 49ers organization is pleased to make that transition alongside a partner as influential as Cumulus.”

“We are most pleased to announce this historic 12 year partnership with the San Francisco 49ers.  We will bring together Cumulus’ iconic Bay Area media brands of KNBR, KGO and KSAN to bring unparalleled coverage of the 49ers, one of the premiere brands in all of sports”, said Dickey. “While the trend in radio has been for shorter deals with sports teams, this 12-year partnership demonstrates the commitment of KNBR and Cumulus to the 49ers, and further cements KNBR as The Sports Leader in Northern California” for almost 25 years.”
